His neck remains sore after he injured it late in the Jets' 30-23 loss at New England last Sunday. Wesley Johnson and Dakota Dozier have split snaps at center all week, although coach Todd Bowles has not determined who would start if Mangold can't.
Wide receiver Eric Decker, second on the team with 24 catches, is questionable with a sore knee.
With Decker's injury and Chris Owusu (concussion) and Devin Smith (ankle) out, the Jets have just three healthy wide receivers: Brandon Marshall, Jeremy Kerley and Kenbrell Thompkins.
