NORMAN, Okla. — At least two Oklahoma athletes were injured during a brawl at a local nightclub that police said involved guns, knives and tire irons.

Details were immediately unclear, but the university characterized the players as victims in the early Sunday incident at the Sooner Knights club in southwest Norman.

"I'm not commenting. There was an incident where a couple of our athletes overall were assaulted. Outside of that, there's an ongoing investigation, so until we know more, I'm not going to confirm or not confirm anything," Oklahoma football coach Bob Stoops said Monday after practice.

Norman police said they went to the nightclub at 2:32 a.m. Sunday, about four hours after fourth-ranked Oklahoma beat Chattanooga 57-2 in its season opener, after "numerous calls to the police department reported subjects fighting with knives, guns and tire irons." Police reported two people had been stabbed and a third had been hit by a car.

One arrest was made: Terran Jason McCabe, 27, was booked for carrying a concealed weapon and released on bail Sunday.

Norman Regional Hospital spokeswoman Brenda Finkle told The Oklahoma Daily student newspaper that freshman defensive end Frank Alexander was treated and released Sunday. The newspaper also cited "multiple student sources" in reporting that freshman basketball guard Ray Willis was injured in the altercation.

Stoops, basketball coach Jeff Capel, athletic director Joe Castiglione and university President David Boren all issued statements but none identified the players involved.

"The health concerns for all of those involved obviously take precedence over everything else at this point. We understand that the outlook is good," Stoops said. "We certainly will encourage anyone with knowledge of this event to assist in the investigation."

Capel thanked students and medical personnel for their assistance "and the police who are working to bring the perpetrators to justice."

"We are most concerned about the recovery of those who were injured. Our desire is to assist law enforcement authorities in their investigation. While the details are still emerging, indications are that those who were injured were victims of assault," Castiglione said.

Boren said he was asking vice president of student affairs Clarke Stroud to work with the athletic department to prevent similar situations.
