MINNEAPOLIS — Two sticky notes dangle from the bottom of a flat-screen monitor in Joel Bauman’s off-campus apartment. In large printed handwriting, one reads, “I Will Inspire,” the other, “I Will Impact.”

“I have them all over the place,” said Bauman, a 21-year-old redshirt sophomore wrestler at the University of Minnesota. “In my car. In my notebook. It’s something I remind myself every day to live my life by.”

Bauman aspires to inspire through his music, mainly hip-hop and rap. His most recent song video, “Ones in the Sky,” which has a positive message and urges people to pursue their dreams, has drawn more than 47,000 hits on YouTube. It can also be downloaded for 99 cents on iTunes. That is a problem for the N.C.A.A.

Because Bauman performed under his own name and identified himself as a Minnesota wrestler, the N.C.A.A. ruled him ineligible for the remainder of the season. J. T. Bruett, Minnesota’s compliance director, said Bauman violated an N.C.A.A. bylaw prohibiting student-athletes from using their name, image or status as an athlete to promote the sale of a commercial product.
