Coach Raheem Morris called wide receiver Drake London pretending to fire a gun, just over a week after the team honored victims of the shooting at Apalachee High School, “a mistake.”

Falcons wide receiver Drake London was penalized after catching a touchdown pass in the final minute of Atlanta’s 22-21 victory in Philadelphia on Monday night for pretending to shoot in the air, a violation of a longstanding NFL rule that prohibits such gestures.

The Atlanta Falcons stunned the Philadelphia Eagles in Week 2 walking away with a 22-21 victory on Monday Night Football. Kirk Cousins led a game-winning drive taking the team 70 yards in 1:05 and threw a touchdown pass to Drake London to tie the game at 21.
