Tuck did say during his weekly radio spot on WFAN that his gut feeling is he will be on the field on Sunday.
"I haven't heard (yet)," Tuck said about the results of the MRI. "I'll talk to the (doctors) tomorrow but as of right now, I don't know."
"I played on one leg," he added. "It's trying to fight through it. Unfortunately I wasn't able to go 100 percent but I'm proud of my teammates and proud of how we fought and we got the victory, that's the main thing and the only thing matters."
Tuck has battled through neck and groin injuries this season. If he is unable to play, the Giants could play the Redskins in a crucial divisional game without two of their top three defensive ends. Osi Umenyiora has missed the last two games with a sprained ankle and a source believes the defensive end will not be able to play Sunday against Washington. After injuring his ankle against New Orleans on Nov. 28, Umenyiora's timetable for recovery was believed to be between two-to-four weeks.
Both Tuck and Umenyiora missed the Giants' season-opening 28-14 loss to the Redskins back in September due to injuries. The Giants (7-6) started Jason Pierre-Paul and Dave Tollefson at defensive ends during that loss.
"I'm as stubborn as they come and if I can get on the football field, I'm going to be there," Tuck said. "If it continues to go at this rate, it will get to a point where we have to worry about it but the frustrating thing is the Green Bay game I felt better than I had all year, like over the hump, but another setback."
"It feels OK, I'll say that," Tuck added. "It doesn't feel as bad as it did last night."
"We are hoping but we will have to wait and see," Coughlin said about Umenyiora, Phillips and Baas. "This stuff is day to day and you get excited and then you get a report and it is not quite as positive as you thought it might be. We will wait. It is early. We got tomorrow and, treatment-wise, Wednesday before we get onto the field. Let's just see how that plays out."
Ballard said he jammed his wrist on his 18-yard catch that put the Giants down to the Dallas one-yard-line which set up the team's game-winning touchdown run. The tight end underwent X-rays and said the results were negative.
"I think Jake is going to be OK," Coughlin said. "He may have injured his wrist a little bit but they don't believe it's much."
Coughlin said Diehl has been dealing with a hand issue.
"Dave just keeps hanging in there and pounding away," Coughlin said. "I think they may be a little bit restricted this week but they'll definitely be ready to go. (Diehl) battled and really done well with it."
Tight end Travis Beckum has an injury to his "upper-chest area" and Coughlin said it could be a pain-tolerance issue.
