but the article says
Mathieu has allowed his image to be used on a flyer promoting an event at a local night club, appeared in several promotional videos online and, multiple sources told SI, received benefits at the club that could affect his eligibility
The Mathieu allowed his image part is all an assumption by the writer. He also comments that Freak and Claiborne were on there, both of whom said they either had no knowledge of the party or didn't attend.
Mathieu didn't gain any benefits from anything claimed in the article other than free entrance into a VIP section of a club.
The writer also makes his judgments based of a complaince officer that has "no knowledge of the Mathieu situation"
Basically it's the same thing Alabama was facing in the Menswear case last year. A minor violation with no eligibility at risk.
