The San Francisco 49ers will be without 29-year old cornerback Nate Clements for quite a while and maybe the rest of the year due to a fractured shoulder blade.  Clements had just lost his starting job recently but he was going to still be counted on as the nickel back.  He has played in 7 games this season for the Niners and he has 35 tackles, 2 tackles for a loss, he has defensed 7 passes and he has 1 interception.  Clements has also returned 4 punts for 38 yards (9.5 avg) this season.  This injury will hurt the Niners as Clements was likely going to get his starting job back at some point in 2009.
