USC is investigating an incident involving USC coach Kevin O’Neill, his wife, Roberta, and an Arizona fan. 

According to sources, O’Neill and his wife were involved in a verbal altercation with an Arizona donor. They were kicked out of the hotel, just hours after USC’s win over Cal. 

"We have received some information [Thursday night] about an incident involving coach Kevin O'Neill, his wife and a fan from another school that occurred following our men's basketball game today," USC athletic director Pat Haden said in the statement. "We are looking into this and gathering facts. We will determine what appropriate action is necessary.

O’Neill took over on an interim basis for a year in 2007-08 while Lute Olson stepped away from the team for health reasons and believed he should have gotten the permanent job. 

USC will face Arizona today in the Pac-10 semifinals with a possible NCAA tournament berth on the line for the Trojans.
