ortland center Theo Ratliff missed the Trail Blazers' game Monday night against the Charlotte Bobcats because of a sprained left knee.

Ha Seung-Jin started in his place.

Ratliff was injured Sunday in a loss to Toronto.

Coach Nate McMillan said it's unclear how long Ratliff will be out but said he hopes to have him back at some point after the All-Star break. Also, the Trail Blazers activated Darius Miles, who has been bothered by a sprained left knee.

"We're just shorthanded with Theo being gone so we're bringing back Miles," McMillan said. "We'll rotate him in there. We feel like he's ready."
