Tuck, who injured his toe during a win against the Dallas Cowboys on Sunday but played through the pain, has said he will likely be a game-time decision against Washington.
Tuck participated in Friday's practice to a limited extent and coach Tom Coughlin thought he looked "okay."
"He did okay," Tom Coughlin said. "He did a few things and he did okay. I don't think there's any setback."
Tuck himself did not speak after the practice, but his shirt spoke volumes.
The Giants ruled out four players in addition to defensive end Osi Umenyiora, who was ruled out Thursday. Linebacker Mark Herzlich, center David Baas, tight end Travis Beckum and safety Derrick Martin will join Umenyiora on the sidelines against the Redskins.
