NEW YORK — Miami Heat rookie Michael Beasley was fined $50,000 by the NBA today for his involvement in an incident at the Rookie Transition Program this month.

The NBA also said that Beasley failed to cooperate with the a league investigation of the matter also involving Miami's Mario Chalmers and Memphis' Darrell Arthur.

Arthur and Chalmers, former Kansas teammates, were fined $20,000 apiece last week after being banished from the rookie symposium.

Security at the resort near New York where the event took place found Arthur and Chalmers in a room with two women, and the scent of marijuana was detected. No drugs or drug paraphernalia were found, but having guests in the room violated NBA policy, and the two rookies were sent home. Arthur and Chalmers apologized but denied using marijuana.
