Michigan sophomore Mitch McGary says he tested positive for marijuana during the NCAA tournament and plans to forgo his final two years of college eligibility.

Coach John Beilein announced McGary's decision Friday, saying the 6-foot-10 forward would enter the NBA draft.

McGary says in a statement issued by the school he made a "poor decision" and was notified of the marijuana test result after the Final Four. He says he regrets disappointing family, coaches and the administration, but all have been "understanding and helpful."

McGary turned down a chance to enter the draft last year as a likely first-round pick and ended up having back surgery last season, putting his standing as an NBA prospect in doubt.

Beilein says McGary "injected an enthusiasm that cannot be matched."
