The Bills filled the last available spot on their practice squad today by signing offensive lineman Keith Williams.
The 6-foot-5, 330-pound Williams is no stranger to the Buffalo offense, having spent 13 weeks last season on the practice squad and the entire 2012 offseason with the team. Williams was among the final roster cuts at the end of the preseason.
Williams, a former sixth-round draft pick by the Pittsburgh Steelers in 2011, played in all four preseason games for Buffalo this summer, mostly at right guard.
The Bills had an opening on the squad after promoting center David Snow to the 53-man roster late last week.
