(Dallas, TX)  --  Trail Blazers big man LaMarcus Aldridge is probable for tonight's season finale at Dallas.  The team says forward Nicolas Batum is out for the game after an MRI revealed a "contusion" in his right knee.  The test did not show ligament or tendon damage, which means Batum will likely be available for the playoffs.  Aldridge has missed the Blazers' last two games with a sprained left foot.
