Yahoo and the Associated Press have reported that Beasley is being treated for depression-related issues at a rehabilitation facility in Houston where he checked in last week.
It's unknown how long the former Kansas State Wildcat will remain at the facility, or whether he will be available when the Heat opens training camp on Sept. 28.
Locally, K-State basketball coach Frank Martin said in a prepared statement today, "As a rule, I do not comment about the private lives of my student-athletes, either current or former. However, Michael like every student-athlete I've coached, will always have my undying support."
Beasley averaged 26.2 points and a national-high 12.4 rebounds as a freshman at K-State in 2007-08 before being selected No. 2 in the 2008 NBA Draft.
Last Friday, Beasley was shown on his Twitter account displaying a new tattoo across his shoulders. In addition, the image showed what appeared to be a small plastic bag on a table. The contents were unclear.
On his Twitter page were these comments: "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."
Beasley's account has since been closed. Beasley, who carried a $4.1 million contract in his rookie season, averaged 13.9 points and 5.4 rebounds in his rookie season. Both were top-five averages among NBA rookies.
On a Twitter page of Michael Beasley Sr., was this message: "Please pray for him, he needs it."
Even prior to Beasley's rookie season, he was in trouble when fined $50,000 by the NBA last September after security officers at the league's rookie symposium detected the scent of marijuana in a hotel room occupied by Beasley,
Beasley told The AP in January that there were times during his first six months as a professional that he felt "everyone was against me" and that many things "get blown out of proportion" - referring specifically to the rookie symposium incident.
