Michael Beasley of the Miami Heat has been fined $50,000 for his involvement in an incident at the league’s Rookie Transition Program earlier this month, and for his initial failure to cooperate with a league investigation of the matter.

Beasley was involved in the same incident for which Miami’s Mario Chalmers and Memphis’ Darrell Arthur were previously fined.

UPDATE: The Palm Beach Post (Chris Perkins) reports: “According to NBA sources, Beasley was in a hotel room with Chalmers, Arthur and two women when the incident took place, but he might have been hiding. The incident occurred when hotel security investigated a smoke alarm going off. When they used a pass key to enter the room, they smelled marijuana. No drugs were found, and Chalmers and Arthur denied using any. Beasley intially was cleared by the NBA, but apparently came forward later.”
