Michael Beasley

told his personal manager several days ago that he was working out in Houston because it brought "a change of scenery" from Miami and Washington.

What happened next is a mystery, even to those who know Beasley best.

The Miami Heat forward checked into a Houston rehabilitation facility last week and is being treated for various issues, including depression, a person briefed on the situation told the Associated Press yesterday. The person spoke on condition of anonymity because of privacy concerns, and could not say whether the other issues included drug or alcohol treatment.

"Based on what I'm getting right now, there's a bit of concern," Bruce Shingler, Beasley's manager, told the AP in a telephone interview. "I don't really know what's going on. I just know his mom is on her way to go see him in Houston. That's it. I'm still collecting a lot of information."

It's unknown how long Beasley will remain at the facility, or whether he will be available when the Heat opens training camp on Sept. 28.

Shingler also said he wasn't sure how long Beasley has been in Houston, or specifically why that was his destination.

"From what I know, he was just getting ready for the upcoming season," Shingler said. "The last time I talked to him, everything was going well. All this rehab and all that, I was totally unaware. It all started as he wanted to go work out in a different place because he wanted to get away. Now this, I don't know what's going on."

The spiral appears to have started in earnest Friday, when a photo of the No. 2 pick in the 2008 draft was posted to his Twitter account, in which Beasley displayed a new tattoo across his shoulders. The image also captured what appeared to be a small plastic bag on an adjacent table, the contents of which were unclear.

Beasley was already getting treatment when the photograph - and several comments, including "Feelin like it's not worth livin!!!!!!! I'm done" and "I feel like the whole world is against me I can't win for losin" - were posted on the feed.
