Falcons Coach Raheem Morris calls London pretending to fire a gun – about a week honoring victims of a school shooting near Atlanta – '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.

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.”

Kirk Cousins led a flawless last-minute drive for Atlanta and connected with Drake London for a 7-yard touchdown with 34 seconds left to give the Falcons a 22-21 victory over the Philadelphia Eagles.
