USC has fired men's basketball coach Kevin O'Neill, the school announced on its website Monday.
Longtime USC assistant coach Bob Cantu will serve as interim head coach while a search for O'Neill's successor is conducted.
"I would like to thank Kevin O'Neill for his four years of service to USC," Athletic Director Pat Haden said. "He took over a program under difficult circumstances because of our NCAA issues and, despite that, he was able to do some good things.
"It was hard for me to evaluate him as a head coach until this year when he had enough players and veterans to compete. As the season progressed, it became evident to me that we needed new leadership in our men's basketball program. Despite a nice road win in our last game, I felt it was best to make a change now, with most of the Pac-12 season still ahead of us, in order to re-energize our team.
"I feel confident that Bob Cantu will capably guide our team on an interim basis while we search for a new coach."
