Kraig Urbik not spotted at practice

ORCHARD PARK, N.Y. -- The Buffalo Bills were back on the practice field Wednesday, but guard Kraig Urbik was not spotted.

Urbik has started all 13 games at right guard this season. In Sunday's loss to the Tampa Bay Buccaneers, the Bills replaced Urbik with J.J. Unga for seven snaps.

It's unclear if Urbik is injured. We'll know more at 2 p.m. when Doug Marrone speaks to reporters.
