Philadelphia 76ers center Andrew Bynum will sit out three weeks as a precaution after receiving knee treatment in Germany.
Bynum had injections of plasma-rich platelets that supposedly stimulate healing in arthritis-affected areas in both of his knees. The Sixers said last week he was cleared to play in camp. The team said Monday that Bynum also had a bone bruise on his right knee. He will continue to participate in low-impact conditioning drills.
Bynum came to Philadelphia with an oversized warning label on his achy knees. He's been plagued by problems in the past, one reason he sought out the same treatment called Orthokine in Germany used by former Los Angeles teammate Kobe Bryant and New York Yankees third baseman Alex Rodriguez.
The Sixers acquired Bynum from the Lakers in a four-team deal that saw them ship Andre Iguodala to Denver. He is set to make $16.1 million this season in the final year of his contract.
Bynum is coming off his best NBA season after averaging career highs with 18.7 points and 11.8 rebounds while making his first All-Star team, starting for the West.
