Bradshaw's availability will be based on the amount of pain and discomfort he can handle, and a source who has been in contact with Bradshaw said it is possible he plays as soon as Sunday.
According to a team source, no decision on possible surgery has been made, and the source in contact with Bradshaw maintains surgery will not be required.
"In the past he has played with the crack or whatever you want to call it, a stress crack in his foot," Coughlin said of Bradshaw, who missed his second straight day of practice. "He has played that way in the past. I don't know what the determination is just yet. We'll have to wait and see."
When he was hurt last week, the Giants said Bradshaw missed time in the second half because a screw from a previous surgery was causing pain in his foot. He was seen on the bench without his right shoe on.
"He is doing good," said Brandon Jacobs, whose locker is right next to Bradshaw. "We still really don't know exactly what is wrong with him. I didn't go into depth, I just feel bad for him. I wish he would heal up and get back our here."
Bradshaw is expected to consult with Dr. Robert Anderson, a North Carolina orthopedist who examined Bradshaw in 2009.
Bradshaw has 440 rushing yards with five touchdowns this season.
Jacobs, who lost his starting job to Bradshaw for most of last season, and lobbied for more carries last week, would not rule out the possibility of Bradshaw playing Sunday.
However, he also plans to be ready to play.
"Yeah, yeah, it looks like I will get my opportunity to play more," Jacobs said. "First off, I want to be able to go out and help the team as much as I can, go out and perform to the best of my ability and when the opportunity is given to me to take advantage of it."
If he is sidelined, expect the Giants to rely on a running back combo of Jacobs and D.J. Ware. Jacobs played this past Sunday for the first time in two games, rushing for 10 yards on four carries.
