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 equipment 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.
