Possible violation for Tyrann Mathieu

BATON ROUGE, La. -- Former LSU cornerback Tyrann Mathieu might have violated NCAA rules by promoting a nightclub while he was still a member of the team, Sports Illustrated reported.

The magazine reports that Mathieu appeared in a video made by a group of his friends known as "Era Nation" in which he promoted 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 star Morris Claiborne, now with the Dallas Cowboys, and current LSU 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.

LSU spokesman Michael Bonnette said the school is aware of the promotional material with Johnson's photograph, but does not believe he committed an NCAA violation.

"We are comfortable that Anthony did not know about it," Bonnette said.

Claiborne was done playing for LSU at the time the flier was distributed. As it turns out, so was Mathieu.

He was dismissed from the football team in August for failing a drug test, and entered a treatment program run by former NBA player John Lucas.

Instead of transferring to another lower-division school to play this season, Mathieu re-enrolled at LSU but is not playing football.

Any NCAA issues could affect his ability to return to football with LSU or another school next season.
