A simple search on eBay reveals Heisman Trophy winner Johnny Manziel is far from the only college football player whose autograph is for sale. Pick a star and you can find memorabilia with a supposedly verified signature.

Heisman hopefuls Jadeveon Clowney of South Carolina, Braxton Miller of Ohio State and Teddy Bridgewater of Louisville. The list goes on and on.

The difference is ESPN has reported the NCAA is investigating whether Manziel, the Texas A&M quarterback, got paid to sign autographs, which would violate NCAA rules.

Gamecocks associate athletic director Chris Rogers said Wednesday the school's compliance office looked into the Clowney autographs on eBay and found no violations had occurred. Buckeyes A.D. Gene Smith said school officials determined Miller had not profited from the items found online with his signature. The Cardinals came to a similar conclusion with Bridgewater.

  • Florida State hired Duke administrator Stan Wilcox as athletic director. Wilcox is a former president of the Black Coaches Association.

Muhammad will have to go through the four-day program next summer.

  • Oft-injured Greg Oden signed with Miami after passing his physical. The former No. 1 overall pick said last week that he was accepting the Heat's offer, one that will pay him $1 million this season and includes a $1.1 million player option for the 2014-15 season. Oden's last NBA appearance was Dec. 5, 2009, for Portland against Houston.
