NASHVILLE, Tenn. -- Tennessee State has suspended basketball coach Nolan Richardson III indefinitely for an undisclosed violation of university policy.

Richardson, the son of former Arkansas coach Nolan Richardson, was suspended Friday and did not travel with the team to Ohio State for Saturday's game.

The suspension, first reported by Nashville television stations and The Tennessean newspaper, was confirmed by the university in a statement Saturday.

Assistant Hosea Lewis was to fill in as coach for the Tigers (2-5).

The NCAA is investigating the program for rules violations under Richardson. The inquiry involves allegations of impermissible practice out of season, providing extra benefits to recruits and unethical conduct by a coach.

Richardson is 23-41 since he was hired at Tennessee State in April 2000. He played two seasons at Oklahoma State and was an assistant under his father at Arkansas from 1991 to 2000.
