Police are investigating a report of a rape that allegedly occurred at the home ofNebraska quarterback Tommy Armstrong Jr.

Police say a 20-year-old-woman reported the incident after arriving at a Lincoln hospital Sunday afternoon.

Armstrong told the Omaha World-Herald that police came to his home to interview him, roommate wide receiver Jordan Westerkamp and another teammate, tight end Trey Foster. It's unknown whether anyone else was at the house.

The suspect has not been named by police, and no arrests have been made.

The woman told police she knows the suspect, and police spokeswoman Katie Flood said that person has been contacted.

Coach Mike Riley said he learned of the police investigation Tuesday morning.

"I would like to have known earlier," Riley said.

Riley said he has talked with Armstrong, Westerkamp and Foster. No players were held out of practice Tuesday, the Huskers' first workout of this bye week.

"We will follow exactly what the policies are within the athletic department and our university," the coach said.

Riley said he would likely have little say in decisions about disciplinary action.

The situation has served as a distraction for the team, he said.

"I'm interested in where we're going," he said, "and what will be found."

Armstrong told the Omaha World-Herald that he arrived home at 12:30 a.m. Sunday, after the football game at Rutgers.

"We were at our house partying," Armstrong said.

He said that after the three players spoke to police, a police officer said, "You guys should be fine."
