Buffalo Bills guard Kraig Urbik has been placed on injured reserve with a knee injury, the team announced on Tuesday.

Guard Chad Rinehart has been signed off the practice squad to replace Urbik, a 2009 third-round pick of the Pittsburgh Steelers who was making his second NFL start on Sunday. Urbik had replaced Geoff Hangartner at center in the Bills' 38-14 loss to the Minnesota Vikings.

Rookie center Sean Allen, an undrafted free agent from East Carolina, has been signed to the practice squad.
