University of Oklahoma police are investigating an alleged assault that happened at the football game with Oklahoma State on Saturday.

An OSU equipment manager was allegedly assaulted by a group of Oklahoma fans during the second quarter of the Bedlam game while trying to retrieve the ball following a field goal. He has a broken rib, Jessica Bruno of KFOR reported.

OU police released this statement:

“The OU Athletics Department is aware of the interaction during Saturday night’s game between some fans and an Oklahoma State team staff member. The matter was immediately turned over to the OU Police Department and is under investigation with the athletics department’s full cooperation. No matter the outcome of the investigation, physical contact by any fan with an employee of any team is unacceptable. The department condemns the behavior of the involved fans, and once the individuals are identified, they will be banned from attending any future OU Athletics events.”

A man who described himself as the uncle of the alleged victim posted on social media about the incident at the game.
