Rockets center Yao Ming is trying to stay positive despite yet another injury that has kept him off the floor.

Yao is currently out with a bone bruise in his left foot and recently learned that he'll be out at least another two weeks.

"Be positive," the center said. "It already happened. It could be a lot worse. At least that proves it was a very successful surgery in that area. We just need to deal with another injury."

Yao is concerned about his conditioning as he recovers from the injury.

"It's definitely not enough," he said.
