The suspension is a result of multiple failed drug tests, sources told ESPN’s Jeff Goodman.
CBS earlier reported the suspension was connected to a drug test.
Henderson’s suspension has been “brewing for a few weeks,” said a source with direct knowledge of the situation. The source also said Henderson can come back to the team “if” he meets certain conditions.
“Since the season ended, we have talked a lot about Marshall taking a greater leadership role with our team. With that comes greater responsibility, and he must do a better job of living up to the high standard we expect from him and he desires from himself,” Ole Miss coach Andy Kennedy said in a statement.
Henderson, a 6-foot-2 guard who started his career at Utah and then played at a junior college in Texas before transferring to Ole Miss, helped turn the Rebels into one of the most offensive-minded teams in the country. He led the SEC in scoring and helped Ole Miss win the SEC tournament and earn an NCAA tournament berth for the first time since 2002.
