Jose Calderon is questionable to play on Tuesday after leaving Sunday's game with a mouth injury. Calderon was elbowed in the face by Nets center Mason Plumlee and owners will have to stay tuned for updates. "I don't think it's serious, but I have not gotten an official word on it," said coach Rick Carlisle. "He's OK, but I think there's some stuff in his mouth they're looking at." If Calderon does miss any games, Devin Harris would likely start at PG with Shane Larkin as his primary backup.
