BATON ROGUE, La. (AP) - Sports Illustrated is reporting that former LSU cornerback Tyrann Mathieu might have violated NCAA rules by promoting a night club while he was still a member of the team.

The magazine reports Mathieu appeared in a video made by a group of his friends that goes by the name Era Nation in which he promotes a party at a Baton Rouge club called The Palace on March 10 of this year.

His pictures were also on fliers promoting the event called "Era Nation Album Release Party For Tyrann Mathieu." The flier also featured photographs of former LSU standout Mo Claiborne and current LSU sophomore defensive tackle Anthony Johnson.

NCAA rules prohibit student-athletes from allowing their names or pictures to be used in advertising the sale of a product or service.
