"Yao Ming's comeback was put on hold again on Friday.

A week after Yao sprained his left ankle in the first quarter against the Washington Wizards, an examination found a bone bruise in the ankle that will keep him out at least two more weeks, likely more if he needs to improve conditioning after the time out with the injury before he is cleared to play.

The examination of Yao's surgically repaired and restructured left foot Thursday in Vail, Colo. showed no complications from the procedure or his comeback, with the team announcing that "the area of the surgery in and around the tarsal navicular bone is completely healed and the structural integrity of the foot is intact."

"His foot that was repaired was fine, pristine," Rockets athletic trainer Keith Jones said. "That part is good. The ankle part that was hurting him is more consistent with a bone bruise. We're still looking at a minimum of two weeks from today."

He was limited to no more than 24 minutes in any game and prohibited from playing two games in as many nights while coming back from the surgery and year off.

Yao had been progressing so well that there had been talks about increasing his playing time before he went out with the ankle sprain and bone bruise Nov. 10 in Washington."
