DENVER - Denver star rookie Carmelo Anthony is questionable for Game 5 of the Nuggets' first-round playoff series against Minnesota on Friday because of a sprained left knee.

Anthony was injured in the third quarter of Minnesota's 84-82 victory Tuesday night when he came down on teammate Marcus Camby's foot. Test results Wednesday showed a mild sprain.

"It's 50-50 right now," Anthony said. "I'm going to get some treatments and get some rehab and see how it goes."

The Nuggets trail 3-1 in the series.
