Boston Celtics center Nenad Krstic has a bone bruise in his right knee and is listed day-to-day.
Krstic injured his knee on Thursday night against San Antonio on Thursday and did not play against Atlanta the following night.
He had an MRI on Saturday that was negative.
Krstic was acquired from Oklahoma City at the trading deadline with Jeff Green in a deal that sent Kendrick Perkins to the Thunder. In 18 games with the Celtics, he is averaging 9.3 points and 5.6 rebounds.
