PORTLAND, Ore. — Charlotte Bobcats power forward Byron Mullens has a sore right knee that caused coach Mike Dunlap to sit him for all but the first three minutes of Monday's 122-105 loss to the Portland Trail Blazers.

Mullens said post-game he does not consider the injury a long-term concern. However it limited his mobility, which caused Dunlap to shut him down quickly in Monday's game.

"It was sort of buckling. I could tell in warm-ups," Mullens said. "I couldn't get a good warm-up in because it felt weak. It led over to the game and I couldn't move that well, couldn't cut off of it.

"Coach made a decision to take me out. I never asked to come out."

In Mullens' absence, Jeff Adrien started the second half and Josh McRoberts got 23 minutes. McRoberts finished with nine points and eight rebounds.

"I do think it was the smart thing to do - come out, rest it," said Mullens, who will be a restricted free agent this summer. "At this point in the season, rest it another day. I'll get some stim (electric stimulation) and ice, and I'll be fine."
