EAST RUTHERFORD, N.J. -- New York Giants running back Ahmad Bradshaw has a cracked bone in his foot, but it's not clear if it will keep him out of action.

A source told ESPN NFL Insider Adam Schefter that the injury is not considered serious and that Bradshaw "should play Sunday" against the Patriots. The source said that surgery will not be necessary, and coach Tom Coughlin said no decision has been made regarding the need for surgery at some point.

Coughlin would not say if Bradshaw would try to play on Sunday. He left open the possibility that Bradshaw would seek a second opinion on the injury.

"In the past he's played with a crack, or whatever you want to call it, a stress crack in his foot, he has played that way in the past," Coughlin said. "I don't know what the determination will be just yet. We will just have to wait and see ... what the doctors decide to do."

Coughlin noted that the players participating in practice will play Sunday.

"Well, he is not on the practice field," Coughlin said. "As long as he is not on the practice field, the guys that are out there will perform as if the responsibility will be theirs."

Bradshaw originally suffered the injury in the third quarter of the Giants' win over the Miami Dolphins on Sunday. He returned to the game in the fourth quarter. X-rays after the game showed no structural damage and Bradshaw believed it was nothing serious.

"I got a screw in my right fifth metatarsal two Februarys ago and I think the head of it is just aggravated right now," Bradshaw said after Sunday's game. "I think it will be fine."

In the past, Bradshaw has been able to play on Sundays despite missing practice time during the week due to foot injuries. The fifth-year running back developed a crack in the fifth metatarsal bone of each foot in 2009 but played through the pain to rush for 778 yards in 15 games. He had offseason surgery to put a screw in each foot, as well as to repair bone spurs from his right ankle.
