The AFC championship turf war started early on Sunday.

Kansas City Chiefs stars Patrick Mahomes and Travis Kelce both tossed aside Baltimore Ravens kicker Justin Tucker's stuff as the players bickered over warmup territory pregame.

Video from one of the end zones at Baltimore's M&T Bank Stadium caught the incidents. Tucker placed his ball holder at the goal line before Mahomes jogged up and kicked it away as he threw warmup passes from the end zone.

Tucker and Mahomes then exchanged words before Tucker set the holder back down in the same spot. Mahomes immediately picked it up and tossed it aside.

This did not deter Tucker. Moments later, he'd set his helmet and two balls next to the holder at the same place on the goal line. This time Kelce got involved. The Chiefs tight end grabbed each item and tossed them aside to clear the path for his quarterback to continue warming up.

Tucker watched and smirked as he stretched from a few yards away.

There's plenty of room on the field for players from both teams to go through their warmups. It wasn't clear from the videos why Tucker and the Chiefs players were doing so in the same space.

It was clear that players who project to play a prominent role in who advances to the Super Bowl weren't interested in giving any ground to the other side.
