Clay (knee) won't practice Wednesday.

Wednesday absences have been routine for Clay this season, so we'd expect the tight end to return to a limited session Thursday. Though Clay may end up listed as questionable for Sunday's game against the Raiders, we'd expect him to suit up this weekend. Of greater concern than his Week 13 availability is the tight end's limited impact in the Bills offense of late. Over his last four games, Clay has tallied a modest 12 catches for 55 yards.
