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."
Tyson was arrested Dec. 29 in Scottsdale. A resident of the wealthy Phoenix suburb of Paradise Valley, the 40-year-old was pulled over after leaving a nightclub. An officer found bags of cocaine in his back pocket and another in a pack of cigarettes in his car, according to court records.
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.
* The United States will play in Goteborg, Sweden, for the Davis Cup semifinals, facing the Swedes in an arena where they twice beat the Americans for the title. The surface has not yet been selected for the Sept. 21-23 matches at Scandinavium Arena.

* The U.S. Anti-Doping Agency will test backup urine samples from Tour de France champion Floyd Landis despite the cyclist's protests about the need for the tests and the credentials of the French lab where they will be analyzed. Landis, who tested positive at last year's Tour, said the tests aren't necessary because the primary "A" samples were negative for doping. If the tests must take place, though, he wants them done at the UCLA lab that handles much of USADA's testing. But the machine used for the tests at UCLA is under repair and won't be running by next Monday, which is when the backup samples are to be tested.
* The Greek government plans to install surveillance cameras at all national soccer and basketball stadiums by the start of next season to combat fan violence.

The ban expires today, and Greek league soccer matches resume Sunday.
* A high-ranking Chinese foreign ministry official, Zhai Jun, said any attempt to boycott the 2008 Beijing Olympics would fail, the state-run Xinhua news agency reported. Last month, French presidential candidate Francois Bayrou proposed his country's athletes stay away from the Beijing Games in an effort to make China lean on Sudan's government. American actress Mia Farrow also has called on corporate sponsors of the Beijing Games to pressure China to do more to help stop the violence in Darfur. *
