The Bills have claimed 24-year old OG Keith Urbik off waivers from the Steelers.  He played in all 4 pre-season games (0 starts) for the Steelers this year.  He is a big guy at 6’5″, 323 pounds who is a run blocker first which means he could fit in well with the Bills.  Urbik will have to work his way to the playing field in practice as the Bills are solid at guard in front of him on the depth chart.
