This comes as police seeking the public's help identifying three men involved in a fight between Flyers and Rangers fans outside Geno's cheesesteaks following Monday's Winter Classic game.
Video of the altercation shows a Rangers fan lying stunned on the street.
Investigators say a man in a Flyers jersey is the main aggressor, throwing the first punch after a verbal dispute. Two other men join in the fight, which also involves a second Rangers fan.
The Flyers, through a team spokesman, had no comment.
Authorities say one victim needed stitches for his injuries.
