Tempers are beginning to flare on Sunday night.
During the third quarter of Sunday's divisional round matchup between the Pittsburgh Steelers and Kansas City Chiefs, Travis Kelce dropped a pass, then decided to drop a cheap shot on a Steelers' player.
The Chiefs tight end had a meltdown after dropping a long pass from Alex Smith, then decided to rough up Steelers' corner Ross Cockrell after the play.
Even Kelce's teammate Justin Houston couldn't believe the boneheaded 15-yard penalty he took.
