Ariz. (AP) - Former heavyweight champion Mike Tyson appeared in court Thursday and learned he will go on trial Aug. 20.

Tyson was fresh out of a California rehabilitation facility and said very little during the five-minute proceeding.

"Yes, ma'am" were his only words, after Maricopa County Superior Court Judge Sherry Stephens asked if he agreed to the trial date, which was pushed back 30 days at his lawyers' request.

Tyson did not speak outside the courtroom, where reporters peppered him with questions and followed him to a Cadillac Escalade.

"We're very pleased with Mike's progress in treatment," said Richard Schonfeld, one of Tyson's lawyers. "He's 72 days sober. We're proud of him."
