The University of South Carolina compliance office says no NCAA violations have occurred with junior defensive end Jadeveon Clowney and his autograph.
A number of Clowney autographed items are showing up for sale on the Internet.
An investigation by the university revealed Clowned has not been paid for his signature.
Gamecocks coach Steve Spurrier addressed the controversy following practice on Wednesday night.
"Well, all these guys sign autographs. I sign them. I don't like signing them either, but mine is not as valuable as JD Clowney's or Marcus Lattimore's. But I've tried to tell Marcus and JD to not sign for the autograph guys, but if it's a little kid or a Gamecock person, they'll sign for all of them," said Spurrier.
Pressed further, Spurrier says he's confident Clowney has "followed the rules."
As scandal involving the sale of college athletes' autographs has already embroiled last year's Heisman winner, Johnny Manziel. An ESPN report said he took a fee of $7,500 for autographing several items during the 2013 BCS National Championship game in Miami.
