Terrelle Pryor’s career at Ohio State, which started with so much promise, came to an abrupt and scandal-ridden end Tuesday.

Pryor announced that he would not play for the Buckeyes this season. He had been suspended for the first five games of the 2011 season for breaking N.C.A.A. rules by accepting improper benefits from the owner of a tattoo parlor.

“In the best interests of my teammates, I’ve made the decision to forgo my senior year of football at the Ohio State University,” Pryor said in a statement issued by his lawyer, Larry James, who added that Pryor was not available for comment.
