NASHVILLE, Tenn. -- One week after the Kansas City Chiefs did everything right in the final moments of a game to claim an unlikely victory, they did everything wrong down the stretch in blowing a lead against the Tennessee Titans.

The Chiefs botched one field goal try in the final two minutes and had another one blocked on the game's final play. In between, the Chiefs allowed the Tennessee Titans to go down the field for what would be the winning touchdown of a 35-32 loss.

"We were in position to close it (out) and we didn't get that done,'' coach Andy Reid said of the Chiefs, who took a nine-point lead with 12 minutes left and five-point advantage with 3:14 remaining.

The ending ruined the return of quarterback Patrick Mahomes to the starting lineup. Mahomes threw for 446 yards and three touchdowns after missing 2½ games because of a dislocated right kneecap.

The botched field goal happened with the Chiefs ahead 32-27 with 1:27 remaining. Harrison Butker never got to try a 47-yard field goal after the ball was snapped with holder Dustin Colquitt not ready for it.

"I looked back at Butker and I saw a flash, which was the ball,'' Colquitt said. Colquit scrambled to his feet and threw a pass nowhere near any receiver. He picked up an intentional grounding penalty.

Starting from their 39, the Titans needed only four plays to score the what would be the winning touchdown on Ryan Tannehill's 23-yard pass to Adam Humphries.

The Chiefs still had 23 seconds left and got into position for a 52-yard try. But Tennessee's Joshua Kalu came around the corner to block the kick. The Chiefs' Blake Bell was late getting to Kalu and wondered whether Kalu was offside.

"He got a great jump, whether he was offside or not,'' Bell said. "I was trying to wait until the ball was snapped. It seemed like he was (offside) but I haven't seen (a replay). We've got to be better.''

Butker made two late field goals last week in the Chiefs' 26-23 win over the Vikings.

The Chiefs' once-commanding lead in the AFC West race is down to a half-game. The 6-4 Chiefs will play against the 5-4 Raiders in Week 13 at Arrowhead Stadium.
