31-year old G/T Nick Kaczur of the Patriots has underwent back surgery to repair a bulging disk putting his 2010 season in jeopardy.  He played in 14 games (13 starts) for the Patriots last season and they had him penciled in to start at LG in the place of Logan Mankins who is holding out.  This is a big blow to the Patriots who are seeing their O-Line starting  to crumble for 2010.
