The Giants' offense played its collective heart out against undefeated Green Bay and lost last week.
But that's nothing compared to what Eli Manning and company will have to do Sunday night at NFC East leader Dallas. And they may have to keep their fading playoff hopes alive while playing as short-handed as they've been all season.
Running backs Ahmad Bradshaw (foot) and Brandon Jacobs (hamstring) did not practice Wednesday and are day-to-day, while Mario Manningham (sore knee) took only limited work.
And center David Baas remained out with severe migraines that stem from a neck injury he's battled all season. That may be the biggest loss, as Baas could miss the rest of the year depending on how the past two days of tests come out.
"The migraine-type headaches are new," Baas told reporters.
"I've got to deal with it, and we'll just have to do what's right for the team."
Baas was a last-minute scratch last week. Still, the Giants ran for 100 yards against the Packers and allowed just one sack on Manning, something they'll have to repeat to keep a powerful offense led by Tony Romo, Dez Bryant and fast-rising running back DeMarco Murray off the field.
Shorthanded or not, the losers of four straight are in must-win mode for the final month.
"The mindset is 'looking ahead,'" Manning said. "It doesn't matter what you've done last week or what your record is.
It's what you're playing for, who you have this week. And you have Dallas, Sunday Night Football. That's a big one."
