With the Philadelphia Sixers’ season swirling down the drain, the news only keeps getting worse. According to Andrew Bynum, he experienced more knee swelling last week, and says he may not play at all this season. [Insert sad trombone here.] Bynum also addressed his impending free agency. Per the Delco Times: “Andrew Bynum said he’s experiencing some swelling in his right knee after last week’s 5-on-5 scrimmage, calling it a ‘four- to five-day setback’ and adding that he doesn’t feel the need to play to get his next contract. Speaking at PCOM following the 76ers’ practice Friday, Bynum said his right knee is his concern. For those keeping score at home, that’s the one that had been better and, for the last few months, the left knee (the one he hurt in November while bowling) was the one setting him back. Bynum said he’s not sure if he’ll ever play for the Sixers this season. ‘Now it’s getting really late,’ he said. ‘I don’t know.’ [...] ‘Being healthy is more important than everything else,’ Bynum said. ‘If I am healthy, I’ll get a deal. I have to be able to play and I need to get to the point where I’m healthy to play.’”
