Members of both teams in the AFC championship game are already using gamesmanship tactics ahead of kickoff.

Pregame videos from M&T Bank Stadium showed Kansas City Chiefs quarterback Patrick Mahomes and tight end Travis Kelce getting into it with Baltimore Ravens kicker Justin Tucker during warmups.

One video from NFL Network's James Palmer shows Tucker stretching near the goal line with a row of footballs and his helmet lined up near where Mahomes is getting loose. Kelce walks through the line of balls and throws each one to the side before continuing and tossing Tucker's helmet into the end zone.
