MIAMI — Michael Beasley is apologizing to the Miami Heat, and calling his stay in a Houston rehab facility his "lowest hour."

Speaking out for the first time since returning from spending more than a month getting treated for substance abuse and other issues, the second-year Miami Heat forward says that he spent the offseason "evaluating my life." He also revealed that he does not expect to be subject to an NBA suspension.

Beasley also acknowledged, he's aware that "I messed up."

Beasley will be with the Heat for training camp, which formally opens Tuesday.
