Rookies Mario Chalmers and Darrell Arthur could face five-game suspensions following their expulsion from the NBA's Rookie Transition Program, according to South Florida Sun-Sentinel.

It has already been reported that Chalmers and Arthur have been fined $20,000, just as the Collective Bargaining Agreement suggests.

According to Article VI, Section 4(b) of the NBA's CBA, "When a player, without proper and reasonable excuse, fails or refuses to attend 'mandatory program,' he shall be fined $20,000 by the NBA." That clause also contains the wording "that if the player misses the Rookie Transition Program, he shall be suspended for five (5) games."

Of course, this situation is slightly different.

"That language was put in for a case in which a guy wants to skip it. ?Nothing is definitive until the commissioner makes a decision," NBA Vice President Tim Frank said Thursday.
