Reports yesterday indicated that the Rockets would have to wait another week to find out whether or not Yao Ming will need surgery.
However, a source close to the situation has told me that Yao has been recommended a procedure that would likely cause him to miss the entire upcoming season. This procedure would involve the use of a bone stimulator that would not require tampering with Yao's foot, ultimately allowing Yao to return at a higher playing level. It would also aid in lengthening his career.
The other option would be surgical, in an effort to remove the screws currently in place and re-position the bone. While this could allow Yao to return next season, they would in no way guarantee long-term health.
But again, we'll know what the entire situation is in a week's time.
