Pierce was "shocked" by the news. He practiced on Friday, but experienced discomfort afterwards and was hospitalized for tests. An MRI revealed the injury, which may threaten Pierce's season. His loss is a blow to a Giants run defense that has underachieved all year. Chase Blackburn will likely take over in the middle, with Michael Boley now healthy at weak-side linebacker.

"That injury I think is kind of over and done with," Manning said. "A week off and not practicing and not putting any pressure on the body or the arm definitely helps, refreshes the whole body." Manning is more of a QB2 even in a plus matchup with the Falcons this week.

Bradshaw's partially cracked foot appears to be getting healthier, but he's been pulled off third downs and will likely see a decrease in touches over the next few games. The third-year tailback isn't a fantasy option going forward.

Bradshaw will play against the Falcons, but he hasn't topped 50 rushing yards since Week 5 and stands to lose playing time to Danny Ware on passing downs. We have him ranked as just the No. 38 fantasy option at RB this week.

It's a little different routine this week for Bradshaw, who usually just practices on Fridays before suiting up on Sundays. He was probably limited Thursday, but it's still a good sign for the status of his fragile foot.

Ware is expected to take over as New York's full-time back on third downs, which had previously involved Bradshaw. Brandon Jacobs has averaged 5.35 yards per touch in the Giants' last four games, so his role is unlikely to decrease. The team may be growing concerned with Bradshaw's partially cracked foot. Ware is also considered the club's best back in blitz pickup.

Ross will make his 2009 debut against the Falcons, but probably only as a nickel or dime back. The Giants are expected to keep Terrell Thomas on the first team opposite Corey Webster, at least until Ross proves he's 100%.
