J.R. Smith has a calf strain and limped around Denver's practice on Wednesday

Smith did some treadmill work before practice and sat out much of the on-court session.

"I'm definitely going to play," Smith said. "I don't think nothing can keep me from this game. It's getting better. It's more of a calf strain than anything. I'm doing the right thing, just staying and getting extra treatment. I'll be ready for tomorrow."
