26-year old linebacker Pat Thomas has signed a 1-year deal with the Bills.  Thomas played in 12 games with the Chiefs last season and he made 48 tackles, defensed 2 passes and he had 1/2 a sack.  He has now played in 29 games in his NFL career and he has made 72 tackles, defensed 3 passes, has 1/2 a sack and he has forced 1 fumble.  The Bills hope that Thomas can help out the linebacking unit in 2009 and on special teams too.
