Patrick Mahomes is facing an investigation by the NFL following comments made towards the officials in the team’s 20-17 defeat to the Buffalo Bills.

The Kansas City Chiefs quarterback is being investigated after his furious reaction to an offside call that ruled out Kadarius Toney’s potential game-winning touchdown.

The play in question saw Mahomes fire a pass toward Chiefs star Travis Kelce in the final quarter of the game with the Chiefs down 20-17.

The tight end caught the ball before darting past two Bills players.

In a surprising twist, Kelce then threw a perfect lateral to Toney who made a 49-yard run into the end zone. The throw would have been enough to see the Chiefs win the tie, however, it was ruled that Toney was offside.
