Inactive: Rodrigue Beaubois joins Kobe Bryant

LOS ANGELES -- Rodrigue Beaubois won't play in today's game against the Lakers because of the strained calf he sustained Friday night at Portland.

Coach Rick Carlisle said the belief is that the injury is not serious and the hope is that Beaubois will be in uniform for Monday night's game at Utah. It's a tough time for Beaubois to be dealing with an injury as he tries to solidify a postseason rotation spot in a crowded backcourt.

For the Lakers, Kobe Bryant will sit out his fifth consecutive game with a left shin injury. That means Mavs defensive stopper Shawn Marion's duties will shift to second-year to Devin Ebanks and Metta World Peace, who has been hot lately

"I didn't think he was going to miss this one," Marion said in the pregame locker room.

Marion has had tremendous success guarding Bryant going back to last year's second-round playoff sweep. In two games this season, both in Los Angeles, Marion limited Bryant to 14.5 points and on less than 28 percent shooting. In the Lakers' 16-point win in Dallas last month, Bryant went off for 30 points while Marion sat out nursing a sore knee.
