Yesterday they said he had a soft case on. Some times you were one to limit movement to keep swelling down doing this a couple times a day, and being on the bench they probably thought it was a good idea in case a player came flying in or a round of hi-fives(which I saw him giving with the bad hand).
If it is a sprain it should be just about healed by Wed, it wouldn't surprise me that he would be good to go, but wouldn't surprise me if he sat out one more game just to be on the safe side.
