Welker had a "99 percent" chance of playing, so there's no question he's in.
Welker twisted his neck during the Patriots' 25-17 loss to the Pittsburgh Steelers. It happened with six minutes left in the fourth quarter, where Welker got his final catch, later to be hit around the shoulders and neck area by safety Troy Polamalu.
Welker is playing solid so far this season, with 57 catches for 824 yards and six touchdowns. New England is looking to payback after their perfect season was ruined by a 17-14 defeat in Super Bowl XLII.
