The Bills added a linebacker to their practice squad Tuesday signing Thomas Williams, who fills the lone vacancy on the eight-man unit.
Williams (6'1" 240) was most recently with the New England Patriots this past offseason, but did not make the final roster cut in early September. He spent most of the 2009 season on New England's practice squad after beginning the year on Seattle's practice unit.
Coming from New England, Williams has some familiarity with 3-4 defensive systems.
A former fifth-round draft choice of the Jacksonville Jaguars in 2008, the USC product appeared in six games his rookie season on special teams. He was waived during final cuts the following season, and it was at that point that Seattle signed him to their practice squad before later landing with the Patriots.
Williams played all three linebacker positions in college for the Trojans finishing his collegiate career with 117 tackles, three sacks, four forced fumbles and three interceptions.
Buffalo has now filled out their eight-man practice squad, which had two openings recently after both OL Mansfield Wrotto and RB Andre Anderson were promoted to the 53-man roster.
