Boston center Kendrick Perkins missed the team's loss to Golden State on Friday night with a sprained left shoulder.

Perkins suffered the injury on Christmas Day against the Lakers and has called it "nothing serious".

"I'm just going off feel right now," said Perkins. "I probably could play if it was the playoffs or something. It's a back-to-back. I just felt like I needed to have a few days to rest. It's a little sore more than anything. It's nothing serious."
