Travis Kelce said on his "New Heights" podcast that Baltimore Ravens kicker Justin Tucker violated an "unwritten rule" by stretching and placing his equipment where Patrick Mahomes was getting loose before Sunday's AFC Championship Game.

The tight end said Tucker was "poking the bear."

"If you want to be a f---ing d--- about it, you keep your helmet and your football and your f---ing kicking tee right where the quarterbacks are warming up . ... If you're not going to pick that up, I'll happily move that for you," Kelce said.

Video shows Mahomes throwing Tucker's kicking tee and Kelce kicking the Baltimore kicker's footballs and throwing his helmet away from where Mahomes was warming up before Sunday's game.

Kelce explained the usual pregame routine, where each team gets half of the field to warm up. Kickers and punters are allowed to work on both sides of the field to account for wind and other weather conditions, but Kelce said they are to stay away from opposing players when they do venture to the other side.

"Justin came out and he said it was more of a joking gesture and kind of a fun, competitive [move] and I get it," Kelce said. "He was kind of winking at me, being a d--- about it, trying to get under the skin. ... We just weren't in a joking mood. We were ready to get after it."
