According to Philadelphia Sixers GM Tony DiLeo, fears that Andrew Bynum won’t play at all this season are well-founded. The big fella could even end up under the knife for his injury-plagued knees. The Sixers, says DiLeo, still intend to lock up Bynum for the long-term. Per the Delco Times and Philly Daily News: “Sixers general manager Tony DiLeo said surgery for Andrew Bynum is ‘certainly an option,’ though the organization is trying to determine the appropriate next step for their injured center and his balky knees. [...] Friday, Bynum said there are no surgical procedures to fix the cartilage issue he’s battling in both his left and right knees. However, DiLeo did not dismiss the notion that going under the knife was a possibility for Bynum. ‘(Bynum) probably knows as much as anyone. He’s seen all the doctors,’ DiLeo said Sunday. ‘Now he has to make a decision, the doctors have to make a (decision) – what’s the next, best step? Is it continuing to rehab? Or go in and do arthroscopic (surgery)? Or is there some other alternative? That’s where we’re at right now.’ [...] ‘[Bynum] is Plan A,’ DiLeo said. ‘Until we get the answers, until we make a decision, it’s a calculated decision or a risk-management decision, that’s something we’ll have to make at the end of the year, going into free agency … [Bynum] is unrestricted,’ said DiLeo, who added that he believes Bynum likes being in the Sixers organization. ‘He can go anywhere he wants and it’s his career. He’s only 25 years old. That’s just something we’ll have to see. We just don’t have all the information now.’”
