Veteran linebacker Pat Thomas, who started nine games last year for the Chiefs, will continue his career in Buffalo.
According to a league source, Thomas has agreed to terms on a one-year deal with the Bills.
He was a sixth-round pick of the Jaguars in 2005, and spent two full seasons with the Jaguars.  He split the 2007 campaign between Jacksonville and Kansas City.
Thomas arrives on the same day that former Bills linebacker Angelo Crowell agreed to terms with the Buccaneers.
