"I feel good," Jacobs said. "The last time I had this injury I couldn't walk the next day and I was out for three weeks. This year it's just a nagging thing that's been there, but I don't think it will hold me out."
An MRI exam showed no structural damage.
"There is no pain and I don't feel restricted," Jacobs said.
"It's tough, but I know the reason they are doing it," Jacobs said. "I'm not necessarily hurt or anything that I couldn't get out there and practice, which I could have if I needed to. But it's precautionary and I'll get out there tomorrow and we'll go from there. I don't know much about further than tomorrow but I know what I'm going to do tomorrow."
"I have a lot of confidence," Jacobs said of Ward and Bradshaw. "I don't think we'll miss a beat. We'll do the same thing. We have a stable full of stallions and they are off and running."
Both Ward and Bradshaw expect Jacobs to play after watching him catch passes from punter Jeff Feagles during the individual drills.
"I practice and prepare myself like I'm a starter every day," Ward said. "I've proven to everybody that I could do it from last year, so I don't think it would be a big adjustment."
Ward gained 154 yards rushing against Chicago last season when Jacobs was sidelined by a hamstring injury.
Bradshaw has spent much of this week taking grief from his fellow running backs after being caught from behind on a 77-yard run on Sunday.
"With Brandon we are a great team," Bradshaw said. "I don't take anything from him. If I am able to get more touches, I plan on taking advantage of it."
The Giants are averaging an NFL-best 172.7 yards per game rushing, gaining at least 200 yards in each of the last three games. They have rushed for at least 200 yards five times.
"I think that you can take either one of those three backs and they can hurt you, so we are concerned enough with all three of them that if Jacobs does not play it won't make any difference," he said.
