One University of Colorado football player is suspended from the team indefinitely and another faces disciplinary action after police say the two were involved in a fight at a fraternity party.

Boulder police cited Tyler Hansen, 19, of Murrieta, Calif., on suspicion of physical harassment, and Vince Ewing, 19, of Carlsbad, Calif., on suspicion of third-degree assault in the incident at the Kappa Sigma Fraternity house, 1100 Pennsylvania Ave., around 1:30 a.m. Friday.

Hansen, a sophomore, nearly replaced Cody Hawkins as starting quarterback this season. He has not been suspended but will face other disciplinary action, CU athletics spokesman Dave Plati said Wednesday. He would not say what measures will be taken against Hansen, calling it a "private team matter."

Ewing, a red-shirt freshman safety, is suspended indefinitely, Plati said.

Both players will have to go through the judicial affairs process at the university, Plati said.

"It's disappointing because we try to take steps so this kind of thing doesn't happen," he said.

According to police reports, Ewing was being physically escorted from a party at the fraternity house by two men because he had tried to hit someone. The men were pushing Ewing from behind when he turned around and pushed one of them -- a hired security guard, Jesse Andrew Kornblum, 22 -- and then punched Kornblum in the jaw, police said.

Hansen had already left the party, but when he saw Ewing fighting with Kornblum, he went back and pushed Kornblum to get him off Ewing, police said.

Hansen and Ewing left the party, and Kornblum called police.

Police said they found Hansen walking on 12th Street and that he was apologetic and cooperative.

Police later found Ewing, also walking on 12th Street, and cited him on suspicion of third-degree assault.

There were signs both players had been drinking alcohol, police said.
