From Marc Spears:
Celtics center Kendrick Perkins had a strong workout during shootaround this morning at the Petersen Event Center in Pittsburgh in preparation for tonight's preseason game against Cleveland. It will be the exhibition debut for Perkins, who had offseason shoulder surgery.
And according to Greg Dickerson, Leon Powe is questionable for tonight's game due to some type of hand injury. I was unable to hear the specifics because I was eating dinner in another room. It doesn't appear to be serious.
