O'Neill, in his second year at the helm of the Trojans, was with his wife, Roberta, when the incident took place at the JW Marriot.

"I'm excited to be back coaching the Trojans and I am looking forward to the postseason," O'Neill said. "This is a special team and we have shown that we can compete with anyone in the country.

"But I temper my excitement of being reinstated with the realization that I made a serious error in judgment the other night. The disciplinary measures that Pat Haden took, including the suspension, were absolutely the right call. My wife, Roberta, and I are both very apologetic for the embarrassment we caused the Trojan Family. We vow to move forward in a positive manner."

Assistant coach Bob Cantu took charge of USC for the rest of the Pac-10 tournament, which ended for the Trojans later Friday night when they lost to Arizona, 67-62, in the first semifinal.

"It was a difficult lesson for Coach O'Neill," Haden said. "I believe the suspension served its purpose and will eliminate any such inappropriate behavior by Coach O'Neill in the future. Although he has been reinstated, Coach O'Neill knows that he still faces additional institutional discipline and a fine."
