NBA training camps just started, and some teams are already having to deal with injuries to their star players. Late last week, we told you about the knee injury that John Wall suffered recently that'll sideline him for the next eight weeks or so. And now comes the news that Andrew Bynum—who the 76ers acquired in the Dwight Howard-to-the-Lakers deal over the summer—will also start off the preseason on the sidelines. He'll be sitting out for the next three weeks after getting injections in his knees in Germany recently that are supposed to help heal the arthritis that he's had to deal with in recent years.

We don't think it's anything to really worry about. In fact, the rest should do a lot of good for Bynum. But, it still sucks to hear about guys missing time just as the season is set to tip off. Hopefully, Bynum won't suffer any more setbacks before the Sixers' 2012-13 campaign starts on October 31 against the Nuggets.
