Deadspin: Dak Prescott forced by NCAA to Sue Company Who Used His Name to Sell T-Shirts

If a student-athlete's name or picture appears on commercial items (e.g., T-shirts, sweatshirts, serving trays, playing cards, posters) or is used to promote a commercial product sold by an individual or agency without the student-athlete's knowledge or permission, the student-athlete (or the institution acting on behalf of the student-athlete) is required to take steps to stop such an activity in order to retain his or her eligibility for intercollegiate athletics. Such steps are not required in cases in which a student-athlete's photograph is sold by an individual or agency (e.g., private photographer, news agency) for private use.

That's the dumbest NCAA rule yet. Couldn't 20,000 OSU fans all independently start marketing/selling Amari Cooper shirts, and what, he's not allowed to play unless he files suit against each and every one of them?
