After spending the past five days receiving treatment on his bruised right ankle, Manu Ginobili returned to the floor Monday ? and promptly hurt his left knee.

Ginobili suffered his knee-on-knee collision less than three minutes into the game. Spurs coach Gregg Popovich briefly replaced him with Michael Finley, but Ginobili returned and finished with four points, four assists and three rebounds in 21 minutes.

"When you're already (compensating) for one leg and you hurt the other, that makes it more difficult," Ginobili said with a laugh. "None of (the injuries) are serious, but, of course, we have to be careful. I don't want to take three steps back."

Ginobili thought his biggest problem Monday was that he played too tentative.

"I was being too cautious to play my game," he said.
