While Manning hopes to play on Sunday, his status will not be certain until game time.
Should Manning be unable to go, the New York Giants will turn to David Carr, the eight-year veteran who has been called everything from franchise player, to bust, to backup quarterback.
But Carr will have to take on another title if his number is called Sunday: the unlikely hero. While many Giants fans hope it will not come to this, the truth is the guy is not so bad.
Take it back to the Houston days, where Carr was still wet behind the ears and ready to lead a new franchise into the record books. Granted, the only record he has is most sacks in a season, but nonetheless, his intentions were good.
But his career there wasn't all that bad. In 2004 Carr threw for 3,551 yards and 16 touchdowns—not bad for a third-year starter. While he also threw 14 interceptions, Houston finished 7-9 and ahead of last place Tennessee.
Fast-forward past the ugly breakup and into the marriage between he and the New York Giants.
In the brief glimpses Giants fans have seen of Carr on the field, he has shown that he knows the game. While his numbers will not blow anybody away, the Giants won't need those types of numbers to win. Remember, they're playing the 1-3 Oakland Raiders, who will be without starting running back Darren McFadden. As well, tight end Zach Miller still has not been cleared to play due to a concussion.
Should Carr be able to just manage the game, limit turnovers, and allow his teammates to flaunt their abilities, the Giants should be able to easily dismantle a team that is dead last in the league in total offense and a defense ranked No. 21 overall.
But perhaps the doubters are still not convinced Carr can pull out a victory on Sunday if Manning isn't able to go. Perhaps some think Carr holds on to the ball too long, forcing him to make bad throws or going down in the pocket.
While this may be true, there is one thing that can remedy that—the best offensive line in football.
The Giants are still fairly healthy up front, and they will not be shown up at home by a team whose only legitimate pass rusher is Greg Ellis.
So relax, grab a beverage, and breathe easy as you watch the Giants go to 5-0, no matter who is taking the snaps under center.
