Buffalo Bills quarterback Derek Anderson (concussion) and tight end Charles Clay (hamstring) have been ruled out for Sunday's game against the New York Jets, according to ESPN's Mike Rodak.
Anderson missed last week's 41-9 loss to the Chicago Bears as well. After signing with the team last month, the veteran started two games, going 0-2 while the team scored a total of 11 points.
Rookie Josh Allen (elbow) returned to practice this week, but it's not clear if he or Nathan Peterman will start.
As for Clay, just once through the first seven years of his career did he appear in 16 regular-season games.
