Just over a week after his twin brother, Paul, dropped from the U.S. men's gymnastics team due to a strained left rotator cuff, Morgan Hamm figured it was best to do the same after aggravating a left ankle injury during training. Both are still battling back from earlier injuries as well; Paul broke his right hand 2 months ago, and Morgan tore a chest muscle back in October. In a matter of 10 days, a strong team has now been reduced to a group of gymnasts with no Olympic experience. Don't count them out of the medal race, but I'm not getting my hopes up either. The Hamms planned to retire after Beijing, so these injuries mean the end of their careers. And some careers they've had. Since the Hamm twins are gone for good, we'll just have to wait to see who can step up to fill the void and maybe lead the U.S. to the podium.
