Use of UW–Madison trademarks by student-athletes is covered in the Temporary Name, Image, and Likeness Policy:
“Student-athletes will only be allowed to use University trademarks, logos, symbols, phrases, slogans, or any other University intellectual property to further the student-athlete’s opportunities to earn compensation for use of her or his name, image, and/or likeness, if those rights have been secured through existing channels and in connection with a valid agreement granting those specified rights. Licensing agreements pertaining to retail products may be sourced through the University’s Office of Trademark Licensing, to the extent the desired rights are available, and are appropriate in the judgment of that Office.”
