Tyson in Rehab

[Harvey]

Mike Tyson has checked himself into an inpatient treatment program for "various addictions" while awaiting trial on drug charges, his lawyer said Wednesday.

"He needed to get involved in something that would help him with his addiction," attorney David Chesnoff said. Chesnoff wouldn't describe Tyson's addictions, but police said the former heavyweight champion told officers that he used cocaine frequently.

Chesnoff said Tyson checked himself into an undisclosed facility shortly after appearing in a Phoenix courtroom.

The 40-year-old Tyson pleaded not guilty on Jan. 22 in Maricopa County Superior Court to felony drug possession and paraphernalia possession counts and two misdemeanor counts of driving under the influence of drugs.

A pretrial hearing is scheduled for Feb. 26.
