1:21 p.m. UPDATED with potential recovery timeframes.

Giants running back Ahmad Bradshaw suffered a cracked bone in his foot during Sunday's game against the Dolphins and is out indefinitely, according to someone informed of Bradshaw's health status.

The person, who requested anonymity because the Giants haven't provided full details on Bradshaw's injury, said the fifth-year veteran is mulling whether to have corrective surgery. Bradshaw has had similar issues with both feet and ankles in recent years and has undergone surgery to insert screws into his feet.

Bradshaw, whose value on the free-agency market this summer was hindered by durability concerns, left the game against Miami to undergo X-rays on his foot and then returned after it was determined one of the screws was aggravating his foot. It was believed he had suffered no structural damage.

It's unclear at this point how long Bradshaw will be sidelined, though the person informed of Bradshaw's injury said he's been telling his teammates he might only be out for two weeks. However, if he undergoes surgery, the timetable will be longer — perhaps the whole season.

In any case, it's obvious the Giants are headed to New England with Brandon Jacobs set to carry the load. Jacobs has struggled this season and gained only 10 yards on four carries against Miami but vowed earlier this week to have a changed attitude that will result in his "scoring these touchdowns" moving forward.

Behind Jacobs on the depth chart are veteran D.J. Ware (45 yards on 14 carries this season) and rookie Da'Rel Scott, who doesn't have a carry in the regular season after rushing for 213 yards and two touchdowns on 14 attempts in the preseason. Against the Patriots' backups in the final preseason game, Scott ran for 114 yards and a touchdown (as well as a 65-yard touchdown on a fake punt).

Tom Coughlin will address reporters after practice, so expect an update on Bradshaw's situation early this afternoon.

Elsewhere, WR Hakeem Nicks (hamstring) was on the bike and watching practice today. I suppose that's a good sign after he wasn't on the field at all for Wednesday's session.

C David Baas (knee) was also on the bike. He won't practice today. Same with OT Stacy Andrews (back), who was not at practice.

DE Osi Umenyiora (knee/shoulder) and WR Mario Manningham (illness) were back to work. It seems FB Henry Hynoski (neck) is good to go as well.
