Rockets center Yao Ming claims that his injured foot is still far from fully-healed despite returning to the floor two weeks ago for the Chinese national team, according to The Houston Chronicle.

"I feel weak," Yao said. "I would say I am about 60 to 70 percent and that is frustrating. I am sure now that I will play in the Olympics."

"But I won't be in my best shape. I know that. And that is disappointing," he added.

He suffered a stress fracture in his left foot in January, missing the remainder of the season for the Rockets.
