MIAMI, Florida, August 25, 2009 (AFP) - Miami Heat's troubled forward Michael Beasley has checked into a Texas rehab facility, the Miami Herald reported on Monday.

The newspaper said that Beasley, the second-overall pick of the 2008 NBA entry draft, has spent the last two weeks in a Houston rehab as part of the NBA's substance abuse program to address concerns over his mental state and drug abuse.

According to the paper, the team is concerned about pictures and messages posted to the player's Twitter page.

The photos show Beasley showing off a tattoo on his back in front of a mirror with two bags on either side which are rumored to be filled with marijuana. The messages reportedly indicated Beasley writing that life was not worth living. Both the picture and the posts have been removed, the paper said.

The paper quotes Beasley's advisor Bruce Shingler saying he was unsure how long the player will be required to stay in rehab.
