The announcement came via Twitter on Saturday night in a post by Missouri's Legion of Black Collegians. It comes after several recent racial incidents on Missouri's campus, and with Wolfe under fire for how he's handled them.
The tweet included a photograph of 32 black men, including starting running back Russell Hansbrough.
"The athletes of color on the University of Missouri football team truly believe 'Injustice Anywhere is a threat to Justice Everywhere,'" the tweet read. "We will no longer participate in any football related activities until President Tim Wolfe resigns or is removed due to his negligence toward marginalized students' experiences. WE ARE UNITED!!!!!"
