The Bills will be without safety Donte Whitner, DE Aaron Schobel and CB Ashton Youboty for a while.  Whitner has a separated shoulder and he will be out indefinately.  Whitner has played in 8 games this season for the Bills and he has 37 tackles, 1 sack and he has defensed 1 pass.  Whitner will be replaced in the starting lineup by Bryan Scott.  Scott has played in 8 games this season for the Bills and he has 21 tackles and a sack.  Aaron Schobel will miss the next 2-4 weeks with foot and bone bruise injuries.  He has played in 5 games for the Bills this season and he has made 19 tackles, had 1 sack and he has defensed 1 pass.  The most serious injury is the one to CB Ashton Youboty who will miss the remainder of the 2008 season as he has a bad case of plantar faciitis.  He has played in 5 games for the Bills this season and he has made 20 tackles, had 1 interception and he defended 2 passes.  These three injuries will really hurt the pass defense of the Bills.
