Chiefs' Xavier Worthy hit with penalty after touchdown, sparks fan frenzy

Worthy appeared to do a Christmas-themed celebration with his teammates, then lifted up his shirt.

NFL officials penalized Worthy for the play. But fans were confused as to why the flag was thrown. Some suggested Worthy may have been pretending to have a gun on him. Gun-themed celebrations have been a point of contention with players.

Mahomes threw his second touchdown pass of the game, an 11-yarder to wide receiver Justin Watson, later in the first quarter.

Worthy has been a bright spot for a receiving corps that's been decimated by injuries. He has 51 catches for 559 yards and five touchdown catches this season. He also has three rushing touchdowns.

Last week, Worthy had seven catches for 65 yards and a touchdown catch against the Houston Texans. It was the second straight week he received double-digit targets. Before the game against the Cleveland Browns, he hadn't had more than eight targets in a single game.

Kansas City will lock up home-field advantage throughout the playoffs with a win on Wednesday.
