Falcons receiver Drake London celebrate a touchdown Monday night by pantomiming shooting a weapon. Paul Sancya/Associated Press In the wake of a touchdown celebration that incurred a potentially costly penalty toward the end of the Atlanta Falcons’ win over the Philadelphia Eagles on Monday night, wide receiver Drake London expressed regrets about having pantomimed firing a weapon into the air. For one thing, the flag for unsportsmanlike conduct moved a tie-breaking extra point attempt back 15 yards.

Atlanta kicker Younghoe Koo was still able to provide the winning margin in the Falcons’ 22-21 victory at Philadelphia, but London and Coach Raheem Morris also pointed out that the celebration unfolded amid a troubling public health issue. “There’s a lot of stuff going around in the world with gun violence that I don’t think I should have displayed there,” London told ESPN. “So I’m not too happy with it, and (you) probably won’t see that again from me.

” As Morris noted during a regularly scheduled news conference at the Falcons’ facility, the team had just honored the victims of a shooting this month at Atlanta-area Apalachee High School. Four people, including two students and two teachers, were killed and nine were injured. Before the kickoff of their season-opening home game against the Pittsburgh Steelers, the Falcons held a moment of silence at Mercedes-Benz Stadium, and some of their players and coaches wore Apalachee T-shirts during warm-ups.
