An Orlando trainer was seen working on the left leg of Gilbert Arenas during the team's game against the Thunder on Thursday night.

The sight caused concern about the surgically-repaired left knee of Arenas, who the Magic acquired in a trade with the Wizards last month.

"We're just trying to keep it loose," Arenas insisted. "With the change of the weather right now, because it's got a little bit of arthritis in it, I can feel it. Before the game starts, we're just trying to keep it warm."
