Ahmad Bradshaw has only had one year in which he’s appeared in all 16 regular-season games. He won’t be making it two this year.

The Giants running back suffered a foot injury during New York’s Week 8 comeback win over Miami. Given his injury history, and specifically his history of foot problems (Bradshaw’s had corrective surgery that placed two screws in his foot), there’s always immediate concern whenever he goes down. However, he was able to finish the game, and he had 27 rushing yards in the fourth quarter, minimizing concern at least temporarily.

Now it’s time to be concerned again, very concerned.

Bradshaw has a cracked bone in his foot, according to the Newark Star-Ledger’s Mike Garafolo, and he’ll miss this weekend’s game against the Patriots. A timetable beyond that is uncertain, with the Giants still silent and waiting to release anything official. But Ralph Vacchiano of the New York Daily News relayed word from several sources who said Bradshaw will be sidelined for “several weeks.”

Vacchiano’s sources also said the fracture is believed to be near where one of the screws that fixed an old fracture in Bradshaw’s foot sits . When screws embedded in bones start piling on top of each other, that’s bad.

Now the Giants will move forward for the foreseeable future with Brandon Jacobs as their primary running back, with seldom used fifth-year man D.J. Ware and rookie Da’Rel Scott behind him on the depth chart. Including his 14 this year, Ware only has 49 career carries, and Jacobs is averaging just 3.3 yards per carry. Scott is still waiting for his first regular-season carry.

This week against a woefully abysmal Patriots secondary the absence of Bradshaw can be overcome by airing it out more often, although the status of Hakeem Nicks also remains highly uncertain due to a hamstring injury. Nicks pedaled on a stationary bike while watching his teammates practice for the second straight day today.

With Domenick Hixon done for the year, the heavy lifting in the Giants’ passing game could fall to Mario Manningham, Victor Cruz, and Jake Ballard, and the latter two are highly talented but still too inexperienced for a prime role in a hostile road atmosphere in Foxboro where Tom Brady and the Pats never lose.

Suddenly a gruesome-looking schedule for the Giants over the next five weeks (Patriots, 49ers, Eagles, Saints, Packers), looks a little more daunting.

UPDATE: So now Adam Schefter is reporting that Bradshaw will be available this week, although the Giants still haven’t confirmed his fracture.
