TEMPE, Ariz. - A Philadelphia Eagles player is facing charges in Arizona after authorities say he pushed a police officer investigating a bar brawl.

Officials said Keelan Johnson, a first-year safety, was arrested early Saturday following a confrontation with officers outside a bar in the Phoenix suburb of Tempe, home of Arizona State University. Johnson played in 49 games for the school.

A probable cause statement says Johnson ''violently pushed'' an officer in the chest, causing him to strike his head against a tree. Police say Johnson appeared drunk and refused officers' orders.

He has been charged with aggravated assault on a police officer, resisting arrest and disorderly conduct.

Eagles spokesman Derak Boyko said the team is disappointed in Johnson's arrest but is still trying to gather the facts.

It was not known if Johnson had an attorney.
