DENVER -- The Colorado Avalanche will be without physical forward Matt Calvert for Game 3 against San Jose on Tuesday.

Calvert was banged up Sunday after taking a hit while delivering a pass to Nathan MacKinnon for an empty-net goal late in Game 2 at San Jose.

Sven Andrighetto will take Calvert's place in the lineup. The second-round playoff series is tied at a game apiece.

Sharks captain Joe Pavelski and forward Joonas Donskoi didn't travel with the team, coach Peter DeBoer said. Pavelski and Donskoi were both hurt during the Sharks' first-round series against Vegas and have yet to play in this one.

DeBoer also said center Gustav Nyquist went home to be with his wife for the birth of their child. He's expected back in time for the game.

RALEIGH, N.C. -- Rod Brind'Amour considers himself lucky to have two goalies he trusts. It looks like he is turning to the second one.

The first legitimate goalie dilemma of the playoffs belongs to the Carolina Hurricanes, now that starter Petr Mrazek is dealing with a lower-body injury that has him day-to-day.

With Mrazek unlikely to start Game 3 against the New York Islanders on Wednesday night, the Hurricanes will try to take a 3-0 series lead behind what could be the first playoff start for journeyman Curtis McElhinney in his 11-year career.

"I think what it is is a luxury that we have a guy that we have equal confidence in," Brind'Amour said Tuesday. "Thankfully, we have that situation. ... We have a guy that we all trust who's been good all year. It's not like we're hoping he's going to be good."

There hasn't been much instability at that position across the league during this postseason, which makes sense -- teams generally don't make the playoffs with shaky goaltending. Carolina became the third team to use multiple goalies, and there wasn't even a whiff of controversy for the two other teams making in-game moves.

Nashville pulled Pekka Rinne for Juuse Saros for the final 45 minutes of Game 4 during the Predators' first-round series with Dallas, and Aaron Dell twice replaced Martin Jones during San Jose's opening-round series with Vegas.

In Carolina, though, an injury has left the Hurricanes with some uncertainty.

Mrazek has started all nine postseason games for the Hurricanes, but he left the last one early with an injury that, as is usually the case in the NHL, has not been publicly disclosed. It was the first time all season that the Hurricanes made a midgame goalie switch.

Brind'Amour calls Mrazek's injury "a nagging thing," adding that "I don't know how long it's going to go, but it shouldn't be too long."

McElhinney stopped all 17 shots he faced to close out Game 2 in just his third postseason appearance.

"It's just gas and go," McElhinney said. "It's one of those things that I've been around long enough and I've been thrown into those situations before. Obviously, the playoff atmosphere's a little bit different but the game itself is still the same. I've felt pretty good all year long."

Less than 12 months ago, nobody saw a Mrazek-McElhinney combination coming, much less figured the pair would backstop Carolina to the verge of the Eastern Conference final.

The Hurricanes brought in Mrazek last July 1 -- the same day they allowed former Conn Smythe Trophy winner Cam Ward to leave for Chicago -- to compete with Scott Darling for the starting job.

When Darling was injured in the preseason finale, Carolina found the 35-year-old McElhinney on the waiver wire and the journeyman fit so well with the Hurricanes that they placed the largely ineffective Darling on waivers and sent him to their AHL affiliate in Charlotte.

Carolina allowed 2.7 goals per game during the regular season. Mrazek stopped 91.4 percent of the shots he faced; McElhinney's save percentage was .912. Both of their save percentages are better than any Hurricanes goalie since 2014 with more than 30 appearances.

It's also worth noting that the last time the Hurricanes made a goalie switch during the playoffs, it worked out pretty well for them.

Carolina began the 2006 postseason with Martin Gerber in net, but while dealing with health issues, he gave up nine goals during the first 75 minutes of the Hurricanes' first-round series with Montreal. Coach Peter Laviolette turned to Ward, who led the team captained by Brind'Amour to the Stanley Cup.

When highly touted Harvard defenseman Adam Fox refused to sign a contract with the Carolina Hurricanes, who had traded for his rights, there was widespread speculation that the New York Rangers were his desired NHL destination. The speculation was accurate: The Hurricanes traded Fox to the Rangers on Tuesday in exchange for a second-round pick in 2019 and a conditional third-round pick in 2020.

Fox, 21, had 48 points in 33 games with Harvard as a junior this season and was named a finalist for the Hobey Baker Award as the top player in collegiate hockey. He also was named a first-team All-American. Fox has played for the United States internationally in world junior tournaments for three straight seasons.

The Hurricanes acquired Fox in a June 2018 deal with the Calgary Flames, along with defenseman Dougie Hamilton and forward Micheal Ferland. Fox opted not to sign with the Flames, who drafted him 66th overall in 2016, after his sophomore season with Harvard. So they shipped his rights to the Hurricanes, who hoped to sign him after his junior season and were unable to.

Once that happened, Hurricanes owner Tom Dundon said the team would "try to trade" the native of Jericho, New York. Fox did have the option of returning to Harvard for his senior season and becoming a free agent in 2020. Instead, he's expected to sign an entry-level deal to play for the Rangers.

A right defenseman, Fox was called the best defensive prospect not currently in the NHL by Carolina general manager Don Waddell when Fox attended the Hurricanes' prospects camp last year. But while Fox is considered a blue-chip prospect, ESPN's Chris Peters had him ranked 30th and behind eight other defensemen on Peters' list of top 50 best young players who were currently not in the league.

"High-end vision, poise and an ability to read plays especially well have all helped Fox become one of the top defensemen in college hockey. He is an assist machine, can quarterback a power play and gets up the ice especially well. Defensively there is room for improvement," Peters wrote.

Fox, 21, joins a Rangers team in the midst of a rebuild. The Rangers own the second overall pick in this summer's draft and have a bevy of strong prospects in their system. Fox should step right into the Rangers blue line and see significant minutes as a rookie next season.

The second-round pick shipped to Carolina is the one the Rangers own. TSN's Bob McKenzie reports that the 2020 third-rounder becomes a second-rounder if Fox plays 30 games next season. Were that to happen, acquiring a pair of second-round picks for a player who didn't want to play in Carolina should take a little of the sting away for the Hurricanes, even if their ultimate goal was having Fox join their impressive collection of defensemen in Raleigh.

Jurgen Klopp has admitted that Liverpool must "suffer" at the hands of Barcelona if they are to stop Lionel Messi from carrying out his "threat" to bring the Champions League trophy back to the Camp Nou.

Liverpool, last season's beaten finalists, face the Spanish champions in Wednesday's semifinal first-leg after cruising past Porto in the previous round to book a place in the last four.

But after destroying Manchester United in the quarterfinals with a virtuoso performance in the home leg a fortnight ago, Messi goes into the clash with Liverpool closing in on fulfilling the promise he made to the Barca fans at the start of the season.

- Hunter: Liverpool have potential to be Barca's kryptonite

- Marcotti: Barcelona's title win about more than Messi

"Last season was really good as we did the double, but we all felt bad about how it went in the Champions League," Messi said in September. "We promise that this season we will do all we can to bring that beautiful trophy back to the Camp Nou."

And although he goes into the game having failed to manage a team to victory against a Spanish club in Spain, Klopp insists that Liverpool can overcome Barcelona and Messi despite the Argentine forward's own determination to lead Barca to glory.

"Messi said at the start of the season that they wanted to bring back this cup," Klopp said. "That sounded already like a threat to me!

"But now we are here, we want to go to the final as well.

"We won't be perfect tomorrow, we will make mistakes, we will suffer, 100 percent. It will be so difficult, but I couldn't be more excited to play and I hope I can transport my players so they feel the same.

"It is not only about Messi, but it is about Messi of course. Can we concentrate on Messi? We should, in certain moments, but then they have 10 world-class players around who can decide the game.

"They have the highest quality team, they are already Spanish champions.

"But we saw the game against Real Sociedad and [Sociedad] did really well. Levante did really well a couple of days ago.

"Barcelona, the better the opponent, the better the competition, the higher the stakes, the more they are in. They are champions of Spain, so now they can focus completely on the Champions League. We are really looking forward to it, but it will be tough."

With Liverpool hosting the second leg at Anfield next Tuesday, Klopp admits the priority is to keep the tie alive for the return fixture.

"I would say that a draw is not the worst result in the world," he said. "Not that we will go for it, but it would be OK.

"So many people came to Barcelona and had an idea on how to play, and in the end they got a proper knock, so we know how tough it will be.

"But two years ago it was a big, big thing for the club to qualify for the Champions League. Now for the second time in a row we are here in the semifinal, that's big.

"It's only positive and everybody sees it like that. We don't need a guarantee.

"But we want to stay in this competition, to get a result tomorrow that gives us a good chance to do it at home. Whatever that result is, we want it."

Liverpool, meanwhile, travelled to Spain with striker Roberto Firmino in the squad after the Brazilian missed last Friday's 5-0 win against Huddersfield with a muscle injury.

"If Bobby is 100 percent ready, then he will maybe play," Klopp said. "He's here, he trained today, we have another session tomorrow. Then I have a decision to make."

Tottenham defender Jan Vertonghen had to be helped off the field shortly after trying to continue to play following a clash of heads in their 1-0 Champions League semifinal loss to Ajax on Tuesday.

Vertonghen challenged for a header in the Ajax area just after the 30-minute mark, but slammed his face into the back of teammate Toby Alderweireld's head, leaving him with blood pouring from a cut on his nose. Vertonghen received treatment on the field and went to change his bloodied white jersey before returning to the game.

Referee Antonio Mateu Lahoz was pointing at his head as he spoke to Vertonghen, before allowing him to return to action in the 38th minute.

He didn't last long before going across to the sideline, leaning over and struggling to stand. He had to be helped down the tunnel by two medical officials and was replaced by Moussa Sissoko.

UK broadcaster BT Sport said that Vertonghen remained in the stadium dressing room after the incident and was being looked at by medical staff.

Following the match, Tottenham manager Mauricio Pochettino said of Vertonghen: "I don't know; I didn't see him. Of course, we will assess in the next few days and will see."

Multiple reports following the match said that Vertonghen passed concussion tests and was also seen walking through the mixed zone after leaving the dressing room.

When asked about allowing Vertonghen to return to the field, Pochettino said it was a decision made by the team's medical staff.

"I wasn't involved, that was a doctor decision," Pochettino said. "I think it's so important things that the rules and the protocol are there and the medical staff follow the protocol. I was never involved, the decision was the doctors and the referee then asked to put him in and said 'go in' and in this action we need to put him out because he didn't feel well.

"Tt wasn't my decision, I repeat. For me, first of all its your life. We must protect the player and of course I was out of the conversation and our medical followed the protocol and decided it was possible to restart the game and it's time to play again.

"But of course it was Jan in that moment and the following action that he started to follow unwell and we check him with the doctor."

Pochettino said he hoped that Vertonghen wouldn't have any more issues following the knock and said he appeared to look OK when he left the stadium.

"He was walking away from the stadium now," Pochettino said. "I hope he is well and you know very well that always you need to keep eyes watching him, others beside him because it was a big knock. I hope it is not a big issue but at the moment he is OK."

Ajax's Donny van de Beek grabbed an early goal to secure a precious 1-0 victory at Tottenham Hotspur in the first leg of their Champions League semi-final on Tuesday.

The 22-year-old struck in the 15th minute to give Ajax a crucial away goal and leave Spurs facing a daunting task in Amsterdam if they are to reach the final for the first time.

Ajax, having already knocked out Real Madrid and Juventus en route to their first semifinal in Europe's elite competition since 1997, were too pacey for a labouring home side, especially in a first half in which they could have put the tie to bed.

Tottenham improved after the break but Ajax defended their lead diligently to restrict the home attack and almost scored a second goal late on when David Neres hit the post.

Erik ten Hag's youthful Ajax side started the match full of energy and purpose with Spurs barely able to escape their own half as they spent the early stages chasing shadows.

Ajax showed just why they had eliminated European giants Real and Juve in the previous two rounds as they sliced through Tottenham's labouring ranks almost at will.

The visitors needed only a quarter of an hour to go ahead as Hakim Ziyech's threaded pass found Van de Beek and the midfielder calmly placed his shot past goalkeeper Hugo Lloris.

There was a suspicion of offside but unlike in Tottenham's epic quarterfinal win over Manchester City, when Raheem Sterling's stoppage-time goal was ruled out, VAR could not save the London side this time as the Ajax fans celebrated.

Van de Beek should have made it 2-0 from Dusan Tadic's pass as Ajax dominated and when Spurs defender Jan Vertonghen was replaced by Moussa Sissoko after a clash of heads with team mate and fellow former Ajax player Toby Alderweireld, it seemed nothing was going right for the hosts.

A Tottenham attack missing the injured Harry Kane and suspended Son Heung-min had looked blunt, with Spaniard Fernando Llorente wasting their best chance when he headed wide from Kieran Trippier's cross.

The introduction of midfield powerhouse Sissoko, deemed not fit enough to start, injected some much-needed energy into Tottenham and he fizzed a shot wide from Llorente's knockdown just before half-time.

Spurs pushed on at the start of the second half and finally began to test the Ajax defence by applying some sustained pressure, with the crowd packed into the stadium responding by raising the decibel-level inside their new ground.

Dele Alli, on the periphery in the first half, volleyed straight at Ajax keeper Andre Onana, then headed over the bar.

Christian Eriksen, yet another former Ajax player in Tottenham's ranks, then played in the overlapping Danny Rose but the left back's shot was charged down.

Spurs were vulnerable to the counter however and Ajax came agonisingly close to doubling the lead, and leaving Tottenham with a near-impossible task in the second leg, when Tadic linked up with Neres whose side-footed shot rebounded off the post.

Considering the way Tottenham struggled at the start of the game, they will still travel with hope next week, especially with their prolific South Korean striker Son available again.
