An MRI confirmed Wednesday that Greg Oden would miss four-to-six weeks with a mid-lateral right foot sprain. So much for the Rookie of the Year award. If you own Oden, there's not much you can do here other than hope that he stays healthy when he returns. Joel Przybilla and Channing Frye will share center duties, but neither appears to be an ideal fantasy option. LaMarcus Aldridge will also get some minutes in the middle over the next two months.
