Members of Maryland’s football team were involved in an altercation at practice on Wednesday, requiring one player to receive stitches, according to a report.

The Washington Post is reporting that Maryland athletic director Damon Evans confirmed there was an incident that occurred during practice. The details aren’t clear, but according to Billy Murphy, the attorney for the family of Jordan McNair, the fight involved a pro-Durkin individual and another player against the head coach’s reinstatement.

Durkin was reinstated on Tuesday but was promptly fired on Wednesday.

According to Murphy, the pro-Durkin player was the instigator of the situation. the attorney made a statement in a video posted on WUSA 9’s Facebook page.

“He punched him viciously in the face,” Murphy said. The player reportedly needed stitches and received an MRI for a separated shoulder.

“This is an incredibly difficult time for our football student-athletes,” Evans said. “However, we take any matters involving physical altercations extremely seriously. We are talking with the players involved and will take appropriate actions based on facts.”

It’s unclear what sparked the altercation.
