The NFL has issued a final warning to Travis Kelce and Patrick Mahomes, cautioning them against throwing helmets while still on the field.

It’s not clear exactly why the tight end slammed his helmet, but CBS announcer Jim Nantz reported it came after those Raiders scores in the first half. More specifically, when the Chiefs were down to fourth and 5 with 2:43 in the half, they faked a punt and passed for a first down. Kansas City ended the drive with a missed field goal, allowing Las Vegas to keep a 17-7 lead going into the half.

Kelce explained everything on the newest episode of his podcast “New Heights.””Right now, I’m just not playing my best football, and I gotta f––ing lock the f–– in, and be more accountable for him (Andy Reid), and be more accountable for my teammates. I gotta keep my f––ing cool, man, ’cause as a leader on this team, that’s not how you switch the momentum.”

Reid stepped in between Kelce and his helmet before trying to console the star player with the help of Patrick Mahomes.
Kelce finished the game with 44 receiving yards and failed to score a touchdown for the fifth straight game.

The Chiefs still control their own destiny as they seek to secure their eighth straight AFC West title. At 9-6, they hold a two-game lead in the division over the 7-8 Raiders and Broncos, so a win in either of their last two games would lock up the crown again.

Kansas City hosts the Bengals in Week 17 before closing out the regular season on the road against the Chargers.
