Several members of Missouri’s football team have said that they won’t participate in football-related activities until university president Tim Wolfe steps down.

The #ConcernedStudent1950 movement is centered around Missouri graduate student Jonathan L. Butler, 25, who is currently on a hunger strike and willing to die until Wolfe obliges.

Butler and other black students blame the presidentĀ for what they say is the university’sĀ failure to address the rising tide of racism on campus.

Among the players shown in this tweet are Russell Hansbrough, Charles Harris, Nate Brown, Cam Hilton, J’Mon Moore and Aarion Penton among many others.
