The Sixers fear that Andrew Bynum has done additional damage to his knees by bowling recently, according to ESPN's Brian Windhorst.
The news keeps getting worse for the Sixers, whose theoretical franchise center has yet to play a game in their uniform. Bynum admitted to reporters that he recently suffered a "setback" and had "weakened cartilage" in both of his knees, so presumably the Sixers have linked that setback to his bowling. It's weird, it's disappointing, and the story is still developing, so check back soon for an update.
This is why every Lakers fan was laughing when we finally offloaded Bynum for Howard.
