Windhorst got the news from Sixers general manager Tony DiLeo. The center has been dealing with a lingering knee injury that has kept him out this season. The Sixers had hoped that Bynum would have been back in the lineup around the middle of December.
Bynum was traded to the Sixers over the offseason from the Los Angeles Lakers, with whom he spent his first seven seasons in the league. While with the Lakers, Bynum averaged 11.7 points and 7.8 rebounds per game, culminating with averaging 18.7 points and 11.8 rebounds last season.
The trade was made after the Lakers exercised a $16.1 million team option ahead of the 2012-13 season. The Sixers are currently 7-5, 1.5 games back of the first-place New York Knicks in the Atlantic Division. The Lakers effectively replaced Bynum with Dwight Howard and Steve Nash.
