Buffalo Bills defensive end Shaq Lawson has apologized for confronting fans in Philadelphia after the team's overtime loss to the Eagles on Sunday afternoon.

Video circulated on social media of Lawson and other Bills defensive linemen confronting fans at Lincoln Financial Field.

"Those of you who know me know that I'm all about the fans, and I have a lot of respect for the game I play and my opponents," Lawson wrote on Instagram.

"Before the game started yesterday, there was a fan behind our bench, who was making life threatening remarks towards us and our families. We asked Philadelphia security to remove the fan, but he was allowed to stay for the entire game. Eventually, our emotions boiled over, and I made a mistake. For that, I apologize, but there are certain lines that should not be crossed."

A spokesman for the Eagles told the Associated Press on Monday that the matter is being reviewed.
