Portland Trail Blazers big man Zach Collins will have surgery to repair his injured left shoulder, the team announced Saturday.

A date for the procedure is yet to be determined, and a timeline for his return will be set after the procedure.

Collins injured the shoulder during Sunday's win over the Dallas Mavericks and has not played since.

The third-year player out of Gonzaga started the first three games of the season for Portland, averaging a career-high 9.0 points per game on 47.4% shooting and 42.9% on 3s.

DETROIT -- Though Bruce Brown had career highs in points and assists on Saturday night, his coach was just as interested with a stat he didn't pile up.

No turnovers.

Dwane Casey praised his second-year player after a 113-109 victory over the Brooklyn Nets, in which Brown had 22 points and seven assists in his first career start as a point guard.

"That was the key to the game was not letting them get out in transition," Casey said of the turnovers. "He did an excellent job. Him being a point guard, that's why the summer league was beneficial for him, to make sure that he learned to run pick-and-roll, to run the team. He did a good job."

Andre Drummond had 25 points and 20 rebounds, and Luke Kennard finished with 24 points and helped seal the win with a driving basket and two free throws in the final 30 seconds of both teams' second game in two nights.

Drummond had at least 20 points and 20 rebounds for the third straight game and fourth time in seven games this season. He added six assists, five blocks and three steals.

"He's a big guy, and he's skilled under there in terms of rebounding," Nets center Jarrett Allen said. "He knows where to put his body and he knows where to put himself. At the end of the day, he has every skill set needed for it."

Kyrie Irving had his first triple-double with Brooklyn with 20 points, 11 rebounds and 10 assists. He played well late but scored six points in the first three quarters, in part because of Brown's defense.

The game swung wildly in the middle quarters. The Nets outscored Detroit by 15 points in the second quarter, and the Pistons turned it around for a 14-point advantage in the third.

"We were down 14 in the third quarter, but it was nothing but grit and grind to come back the way the guys did," Casey said. "We've got to be that way every night."

The Pistons, who averaged 19.8 turnovers in the first six games, committed eight in the first half, but none after halftime.

Spencer Dinwiddie split a pair of free throws with 7.4 seconds remaining, and Drummond did the same with 6.7 seconds left to put the Pistons up 111-108.

Prince then split a pair, missing the second on purpose, and Drummond grabbed the rebound and made a pair with 3.6 seconds left to seal the win.

"For some reason we ran out of gas in the second half, and I'm not sure why," Nets coach Kenny Atkinson said.

Drummond had 11 rebounds in the first quarter and assisted the first three baskets. His playmaking was a boost for a team short on ball-handlers.

Playing without injured point guards Reggie Jackson (back), Derrick Rose (hamstring) and Tim Frazier (shoulder), the Pistons played Brown and Kennard at the position, with Drummond facilitating from the high post.

"It was a game of opportunity for some guys," Kennard said. "Bruce, the way he stepped up tonight, he was kind of one of our leaders on the court. So credit to the kid. He played his heart out offensively and he was guarding their best player throughout the entire game."

Taurean Prince added 20 points and Joe Harris had 18 for the Nets.

TIP-INS

Brooklyn: Caris LeVert said Friday night's 25-point performance against Houston was in honor of his grandmother, who died this week. LeVert had 14 points on Saturday. ... DeAndre Jordan returned to the starting lineup for the third game this season. Atkinson said before the game that Allen has struggled against Drummond, which could force a change. In three games against Brooklyn last season, Drummond averaged 9.3 offensive rebounds per game.

Detroit: This was Detroit's third different starting lineup in seven games this season. ... The Rev. Jesse Jackson was in attendance.

MONTH OFF

Jackson is out at least four weeks with a back injury, the team announced earlier Saturday.

Jackson, who played the season's first two games but has missed the last four, has a stress reaction in his lower back. The team announced treatment and rehabilitation has started and he will be re-evaluated in four weeks.

All-Star Blake Griffin has missed all seven games with lingering soreness in his left knee and hamstring. It was announced before the season that Griffin would be re-evaluated in early November.

MAKING HISTORY

Drummond became the third player in the last 25 years to have three straight 20-point, 20-rebound games, joining Kevin Love and DeMarcus Cousins.

There has been only one other 20-20 game this season, by Anthony Davis of the Los Angeles Lakers.

TRIP DUB

Irving now has three career triple-doubles. He's now had one with each of his three career teams, Cleveland, Boston and Brooklyn.

UP NEXT

Brooklyn: Host New Orleans on Monday.

Detroit: The Pistons will close their second stretch of three games in four days this season Monday at Washington.

OKLAHOMA CITY -- New Orleans Pelicans forward Brandon Ingram left Saturday's game against the Oklahoma City Thunder midway through the second quarter with a head injury and did not return. Ingram was apparently struck in the head at some point during play and asked the bench for a sub. At the first dead ball, Ingram checked out of the game and went directly into the locker room and remained there for the rest of the game.

Ingram's specific injury wasn't initially clear, with the team saying he was still being "evaluated" some 30 minutes after the game.

"I haven't seen it at all," coach Alvin Gentry said. "Just got hit in the head, that's it."

Ingram, 22, had 7 points and 4 rebounds in 13 minutes before checking out. Without Ingram, the Pelicans struggled to score in the second half, putting up just 44 points in the final 24 minutes -- including 18 in the fourth quarter -- in a 115-104 loss to the Thunder.

After being acquired in the blockbuster Anthony Davis trade, Ingram has gotten off to a good start in New Orleans, averaging 26.8 points and 8.2 rebounds in his first five games.

Already short-handed without No. 1 overall pick Zion Williamson and forward Derrick Favors, the Pelicans fell to 1-5 with Saturday's loss.

World Series MVP Stephen Strasburg is opting out of his contract with the Washington Nationals, sources familiar with the situation tell ESPN's Jeff Passan.

Strasburg had four years and $100 million left on a deal he signed in 2016. He faced a Saturday deadline to opt out.

The 31-year-old enters free agency fresh off a regular season in which he posted a career-high 18 wins and led the National League with 209 innings pitched -- no small measure for a pitcher who has battled injury throughout his career.

He continued rolling in the playoffs. He became the first pitcher in major league history to win five games in a single postseason without a loss, his 47 strikeouts were tied for the second-most in a single postseason (Curt Schilling had 56 in 2001), and he posted a 1.98 ERA in six appearances overall.

The right-hander won two games in the World Series, including a pivotal Game 6 in Houston in which he became the first starter to go at least eight innings in a World Series since Matt Harvey did so in Game 5 in 2015. The following night, Washington won Game 7 and Strasburg became the first No. 1 overall draft pick to be named World Series MVP.

Opting out doesn't mean Strasburg won't return to Washington, which drafted him out of San Diego State in 2009. But he'll at least test the free-agent market, which will be highlighted pitching-wise by him and Gerrit Cole.

Strasburg, who is represented by Scott Boras, is a career 112-58 with a 3.17 ERA and 1,695 strikeouts over 1,428.2 innings.

Washington also must decide what to do with third baseman Anthony Rendon, who is a free agent after hitting 34 home runs, 44 doubles and a major league-best 126 RBIs this past season.

AUSTIN, Texas – Valtteri Bottas put his Mercedes on the pole for the United States Grand Prix Saturday during qualifying at Circuit of the Americas.

Bottas’ first lap during Q3 turned out to be his best, with the Mercedes driver turning in a 1:32.029 lap to secure his fifth pole of the season.

“This is very satisfying – it’s been a while since we’ve last been on pole, so this is a great feeling,” said Bottas. “I was struggling with the car yesterday, but we’ve made a number of changes overnight and today the car felt much better. I knew going into qualifying that the car had the potential to fight at the front, I just had to get a good lap together. I’m very pleased with my first lap in Q3; it wasn’t quite perfect, but good enough to put us on pole. It’s always an advantage to start from the front; now it’s up to me to try and maintain the lead at the start tomorrow. Our long runs looked good yesterday, so hopefully we can get a strong result in the race.”

Just like Bottas, the first lap turned out to be the best lap for everyone during Q3. Sebastian Vettel’s first lap was enough to earn him the second starting position, only .012 seconds shy of the lap put down by Bottas.

Red Bull’s Max Verstappen qualified third, meaning three different teams took the top-three starting positions in Sunday’s race.

Charles Leclerc was fourth for Ferrari, while championship leader Lewis Hamilton was shockingly fifth following the final round of qualifying after he paced Friday’s round of practice sessions.

Red Bull’s Alexander Albon, McLaren’s Carlos Sainz Jr. and Lando Norris, Renault’s Daniel Ricciardo and Toro Rosso’s Pierre Gasly completed the top-10 in qualifying.

FORT WORTH, Texas – Kevin Harvick will start the defense of his AAA Texas 500 win from the top starting position on Sunday afternoon at Texas Motor Speedway.

Harvick crushed the competition en route to his sixth Monster Energy NASCAR Cup Series pole of the season Saturday evening during qualifying, with a lap of 28.465 seconds (189.707 mph) in the No. 4 Busch Beer Ford Mustang.

The pole is Harvick’s second at Texas and the 31st of his Cup Series career. He’ll seek a second-straight victory that would advance him into the Championship 4 on Sunday.

“I think the key to the lap was obviously knowing that you had to be wide open,” noted Harvick. “We did a halfway qualifying run yesterday and worked most of the day on race runs and making sure we ran enough laps to know where our car was. I think the first pit stall is obviously a good stall to have here for pit road time and the things that go with that, because I think it is going to be a track position game like it was last time.

“Hopefully this pole and that first pit box help us stay on the right side of that come Sunday afternoon.”

Erik Jones, who was eliminated in round one of the playoffs, will join Harvick on the front row Sunday after posting a time of 28.588 seconds (188.890 mph) with his No. 20 Sport Clips Toyota Camry.

Jones’ Joe Gibbs Racing teammate Denny Hamlin rolls off third (28.615/188.712), followed by the Chevrolet duo of Kurt Busch and Alex Bowman.

Four Ford Mustangs – driven by Aric Almirola, Daniel Suarez, Brad Keselowski and Ricky Stenhouse, respectively – qualified sixth through ninth, with Matt DiBenedetto’s Toyota completing the top 10.

Eleventh through 15th are five of the remaining playoff drivers, with defending Cup Series champion Joey Logano leading that rostrum. Kyle Busch, Kyle Larson, Chase Elliott and Ryan Blaney ended the time-trial session just behind Logano.

Notably lowest of the playoff drivers, Martin Truex Jr. qualified 17th Saturday evening, but is already locked into the Championship 4 thanks to his win last weekend at Martinsville (Va.) Speedway.

The AAA Texas 500 goes green at 3 p.m. ET Sunday, with live coverage on NBCSN, the Performance Racing Network and SiriusXM NASCAR Radio, channel 90.

BOSTON -- Ottawa forward Scott Sabourin has been transported to a hospital for evaluation after being taken off the ice on a stretcher with his head immobilized following a collision with Boston forward David Backes early in the first period of Saturday night's game between the Senators and Bruins.

The Senators sent an update on their Twitter feed that Sabourin was conscious and speaking with the attending doctors while leaving the arena.

He gave the crowd a brief "thumbs up" as he was leaving the ice.

Sabourin had skated up to make a hit on Backes when the players' helmets collided. Sabourin immediately fell to the ice, appearing to be unconscious, and he lay motionless for a brief period.

Medical staff from both teams rushed to Sabourin, and a Bruins trainer quickly signaled for a stretcher. There was a large blood spot on the ice under Sabourin's face.

TV cameras showed Backes visibly upset, looking as if he was fighting back tears as he watched medical personnel attend to Sabourin. An Ottawa player could be seen consoling Backes, putting his glove on his shoulder. Most of the players on both teams took knees in front their benches and skated over to Sabourin when he was finally put on the stretcher after a delay that lasted about 10 minutes.

Fans gave Sabourin a loud ovation when he was taken from the ice. Backes went to the dressing room after Sabourin was wheeled off.

The Bruins announced in the second period that Backes had an upper-body injury and would not return.

There was no immediate word on Sabourin's injury or condition.

THOUSAND OAKS, Calif. – Retief Goosen shot a 6-under 66 on Saturday to take a one-stroke lead over fellow Hall of Famers Fred Couples and Bernhard Langer into the final round of the Invesco QQQ Championship, the second event in the PGA Tour Champions' Charles Schwab Cup playoffs.

Goosen birdied five of the last seven holes on the front nine at Sherwood Country Club, added a birdie on the par-5 11th, bogeyed the par-3 12th and rebounded with a birdie on the par-4 14th. The 50-year-old South African, the Senior Players Championship winner at Firestone in July for his first senior title, had a 10-under 134 total.

"I was walking down No. 6 or so and you see Langer's name at the top of the board and you know now you've got to put your foot down," Goosen said. "Luckily, he stumbled a bit coming in, but I also sort of stumbled a bit. It's going to be nice going up against Freddie and Bernhard tomorrow."

Langer, the 62-year-old German star who has won the season Schwab Cup title five times, matched Couples with a 65. Langer closed with a bogey, and Couples finished with a birdie.

"I hit it a little better, a little closer and made some putts, that was really the difference," Langer said. "Just sour to have finished with a bogey there on the last. Not the way to finish a day like that, but played really well, did everything well."

The top 36 in the standings will advance to the season-ending Charles Schwab Cup Championship next week in Phoenix. Goosen began the week seventh, Langer fourth and Couples 32nd.

"If you want to take away that Charles Schwab Cup, you have to win these last two events," Goosen said. "I sort of feel like my game is there, although earlier in the week I hit the ball horrible, but my swing got better as the week went on. Today was nice. I played the par 5s horrible, but otherwise the rest of the course good."

The 60-year-old Couples won the last of his 13 Champions titles in 2017.

"I hit a lot of very good irons and it was an easy 7 under," Couples said. "Really the only bad shot I had was on the 10th. It was probably the easiest shot I had, it was a 100-yard sand wedge and I missed the green to the right and I made a really great up-and-down. Then the round just kept going and I made a few birdies in a row."

Miguel Angel Jimenez, tied for the first-round lead with Billy Mayfair and Woody Austin after a 66, had a 70 to fall into a tie for fourth with defending event champion Scott Parel at 8 under. Parel shot 66.

Jimenez won the playoff opener two week ago in Virginia and is 10th in the season standings. Parel is eighth.

Charles Schwab Cup leader Scott McCarron was 5 under after a 69. Second-place Jerry Kelly had a 70 to get to 2 under.

Austin was 5 under after a 73. Mayfair had a 75 to fall to 3 under.
