Several sources told ESPN's Chris Broussard on Thursday that NBA Commissioner David Stern was so angered by Mario Chalmers and Darrell Arthur's alleged involvement with marijuana and women at the rookie transition program that he made the call himself to remove them from their rooms at the Doral Arrowwood resort in Rye Brook, N.Y.

According to sources, Chalmers and Arthur were caught in Arthur's room at the Doral Arrowwood resort in Rye Brook when a smoke alarm went off Wednesday at about 2 a.m. Hotel management went to the room, but the players refused to allow them in.

The police were called to their room, which they searched, but neither marijuana nor drug paraphernalia was found. Representatives from the players' association were also on the scene by that time.

Chalmers and Arthur were permitted to remain at the resort and were believed to be planning to attend a kickoff address by Stern later Wednesday morning. But after being told of the violations shortly before beginning his speech, Stern immediately had the players removed from their rooms.

Several sources described Stern as being furious.

The commissioner's anger was apparently evident when he began his speech; he mentioned Chalmers and Arthur by name and told the 67 rookies in attendance that the two would be thrown out of the program and forced to attend the 2009 session.
