Fullback Henry Hynoski (neck) sat out during open portion and is unlikely to play Sunday. He missed the Giants' Week 6 win over Buffalo due to the ailment. Backup offensive lineman Stacy Andrews sat for the second straight practice with a back injury.
Also, backup lineman Adam Koets, on the PUP list with a back injury, did not practice.
Tuck, who has missed four of the Giants' six games with neck and groin injuries, said on Thursday that "the plan" is for him to play. Brandon Jacobs, who sat out the last two weeks with a medial collateral ligament injury, also expects to play against the winless Dolphins.
Pro Bowl guard Chris Snee missed the Buffalo game with a concussion but should be out there on Sunday as well.
