With Smith going on the season-ending list Tuesday, the Bills now have 16 players -- including nine regulars -- on IR. The rash of injuries has contributed to a seven-game skid that's dropped Buffalo (5-9) out of playoff contention for a 12th consecutive season.
Used mostly as a blocker, Smith has four catches for 11 yards in 10 games, including three starts this season. He was hurt in the third quarter of a 30-23 loss to Miami on Sunday.
Smith was drafted in the fifth round by New England in April.
