Nick Mangold has been rehabbing an ankle injury, which he suffered against the Patriots, this week, meaning Dalton Freeman has been seeing the first-team reps at center during practice. Mangold, who was recently named to his sixth Pro Bowl, has missed only two games in his nine-year career. Head coach Rex Ryan said Mangold is likely a gametime decision. Freeman, however, is ready to step in if needed: "Each and every week I prepare as if I'll have to start the game because you never know what could happen. We're still in the process of seeing how Nick's feeling. Obviously he's going to try and go."
