Norman police have identified two University of Oklahoma athletes who were stabbed during a brawl at a local nightclub.

Officers say 18-year-old football defensive end Frank Alexander and 18-year-old freshman basketball guard Ray Willis sustained knife wounds during the Sunday morning altercation at Sooner Knights club in southwest Norman.

Alexander was treated and released from Norman Regional Hospital, but Willis' condition wasn't immediately available.

Police say both required surgery because of their injuries.

Nineteen-year-old Rachel Taylor, who was struck by a vehicle outside, was treated at a hospital and released. No arrests have been made.

Officers say the fight erupted about 2:30 a.m. after a number of people tried unsuccessfully to crash a private party at the club and allegedly attacked invited guests after they were denied entry.

OU football coach Bob Stoops declined comment, except to acknowledge that a couple of athletes had been hurt.
