BOULDER, Colo. -- Colorado football players accused of participating in a sexual assault will not be suspended from the team unless they are charged with a crime.

University and city police are investigating a student's allegation that she was sexually assaulted at an off-campus party attended by football players and recruits on Dec. 7. No charges have been filed.

A player who violated team rules at the party, such as the ban on underage drinking, could be disciplined whether or not he is charged with a crime, Colorado spokesman Dave Plati said Thursday.

Plati said coach Gary Barnett might postpone any suspensions for team rule violations until after third-ranked Colorado plays No. 2 Oregon in the Fiesta Bowl on Jan. 1. Plati said there was a risk the public might incorrectly think a player suspended for a minor violation might have played a role in the alleged rape.

Campus police are leading the investigation because the student approached them first. Boulder police are assisting.
