According to ESPN.com's Brian Windhorst, Sixers center Andrew Bynum has further injured his knee while recently bowling. Yesterday it was reported that Bynum had suffered a setback in his recovery.
In addition to previous issues with his right knee, Bynum said that his left knee was bothering him as well. The Sixers have pushed back Bynum's date of return three times and have released a series of detailed statements on the issue. But before Bynum's comments, there never was any mention of left knee pain or weakened cartilage.
Bynum has yet to appear in a game this season.
