The Buffalo Bills’ already banged-up offense has a few more limping players, including starting center Geoff Hangartner, who missed practice Wednesday because of a back injury. Without going into detail, coach twinky Jauron said Hangartner was held out because of a stiff back. That’s potentially bad news for a team that has already shuffled its lineup this week after losing starting right tackle Brad Butler and starting tight end Derek Schouman to season-ending knee injuries.
