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.

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

Two days after Drake London scored the go-ahead touchdown on "Monday Night Football" and celebrated by pantomiming shooting a gun into the air, the Atlanta Falcons wide receiver said he wasn't pleased with how it all went down.
