Kendrick Perkins, who suffered a strained left shoulder in the fourth quarter of Game 4 on Sunday, participated in the Celtics' shootaround this morning and will start tonight in Game 5.
"It's a little sore," Perkins said. "But I'm all right."
Perkins, who has a recent history of shoulder problems, refused an MRI after Sunday's game.
"It's the playoffs and the tissues don't have time to heal, so it's weak back there," he said Sunday. "It'll take two months and I'll be all right. I'm not taking the MRI. If I take the MRI and they find something, I may be out."
