WALTHAM — Already without Avery Bradley , the Celtics  practiced on Friday without backup guard Keyon Dooling , who was out sick. Dooling returned to the team Saturday morning for its shootaround before Game 7 with the Sixers. The team worked on half-court set as per usual with no conditioning drills. Before the shootaround, the team also watched film.
With Bradley out and Ray Allen  nursing two sore ankles, Dooling figures to see more playing time in Saturday night’s decisive game. In another positive sign, Greg Stiemsma  took part on Saturday, a day after Doc Rivers  said the backup center’s feet were “feeling better.” During Game 6 in Philadelphia, Rivers said that Stiemsma asked out of the game because he was in pain.
“He couldn’t play in the second half the other night,” Doc Rivers said on Friday. “Funny, I put him and he walks up and says, ‘I can’t go.’ I thought he was walking up to go in. But he feels better and that’s good.”
Allen has two sore ankles and Paul Pierce  is nursing a sprained MCL in his left knee. Both Allen and Pierce are expected to start in Game 7.
Meanwhile, Bradley is resting after surgery Friday on both shoulders, a source with direct knowledge of the situation tells WEEI.com. He was the only Celtics player not in attendance at the Saturday morning shootaround.
The source confirms that Bradley had surgery on Friday and is expecting a summer-long rehab program that could last up to four months. If all goes as expected, Bradley should be ready for training camp in October.
Bradley initially injured the rotator cuff in his left shoulder but after playing with the injury, he also injured the right shoulder to the point where it needed to be repaired as well. Bradley had the left shoulder pop out in the third quarter of Game 4 against the Sixers and missed Games 5 and 6 before deciding to have surgery on Friday, performed by team doctor Brian McKeon, so that he could be ready for training camp in October.
