"I thought it was a stinger. It kept hurting the whole rest of the game, but my adrenaline was pumping," Howard said after sitting out of the Lakers’ practice Saturday. "But last night, it was killing me. And I was in a lot of pain this morning. I couldn't put my clothes on.
"Hopefully it feels better so I can play, but if not, I'll have to sit down."
Howard was injured in the third quarter when he was fouled by Clippers forward Caron Butler while attempting a dunk.
Lakers coach Mike D'Antoni said there was a good chance Howard would be available Sunday.
Jordan Hill (ankle) was able to practice and will be available Sunday.
