COLUMBIA, Mo. (AP) — Missouri football players announced on Twitter that they will not participate in team activities until the university president resigns, a move designed to join forces with a black graduate student who is holding a hunger strike.

The statement from the athletes of color on the University of Missouri football team was tweeted out Saturday by several members of the football team, including starting running back Russell Hanbrough.

Jonathan Butler has not eaten since Monday and met with Missouri President Tim Wolfe on Friday to discuss the university’s handling of racial harassment cases.

The statement from the players included a photograph of 32 black men, including Butler.

In a text message statement to The Associated Press, the Missouri athletic department said it was aware of the statement by “many of our student-athletes.”
