The Philadelphia Sixers provided an update on injured center Andrew Bynum, and it’s all bad news. Bynum isn’t expected to practice until sometime in December, and may not play until January. Per the team website: “In mid-September 2012, Bynum suffered a bone bruise of his right knee. He was examined at that time by Dr. David W. Altchek of New York’s Hospital for Special Surgery, Bynum’s longtime personal doctor who is acting as the lead orthopedist in caring for Andrew’s knee. It was initially communicated to the Sixers that Bynum should refrain from basketball activity for a period of four weeks to allow the knee to heal. His knee was re-evaluated on October 22 by Dr. Altchek, who extended by an additional four weeks to November 19 the time for Andrew to refrain from basketball activity. Andrew received a fresh MRI and was seen again by Dr. Altchek this past week on Monday, November 5. At that evaluation, Dr. Altcheck extended Andrew’s return date for a second time by an additional three weeks. [...] If the current prognosis holds unchanged, Bynum would be cleared to resume normal basketball activity by approximately December 10. In addition, the team estimates that Bynum in turn will need an additional 1-4 weeks thereafter for conditioning, training and practice before being able to resume game play with significant minutes.”
