Clarett claimed Buckeyes State Coach Jim Tressel and his staff gave him cars, cash and improper benefits while he was enrolled at Ohio State.
Clarett claims it was arranged for him to receive passing grades and that he received money from boosters as well as from no-show summer jobs.
Most of those allegations, in ESPN The Magazine, were also made during an NCAA investigation that found Clarett lied to investigators.
"I have read the story that appeared earlier today on ESPN.com," said Tressel. "I can say without any reservations that all of the allegations made against me in that story are totally false."
