Ahmad Bradshaw has sprained knee

EAST RUTHERFORD, N.J. -- New York Giants running back Ahmad Bradshaw has a sprained knee, which could keep him out of Sunday's game against the Atlanta Falcons.

Giants coach Tom Coughlin would not rule Bradshaw out for the game, citing the running back's toughness and ability to play through pain. But Coughlin said he would not put any odds on Bradshaw's status, knowing that he is considered perhaps the toughest player on the team.

"I am not going to speculate -- because of the toughness of this young man -- on how long it would be," Coughlin said. "He is very positive about it and definitely wants to get back as fast as he can.

"I am not going to rule him out of anything. I am not going to talk about the percentages or anything like that. You can speculate on that knowing full well what the injury is."

Because of the injury, Bradshaw carried the ball only 11 times for 33 yards during the Giants' 52-27 win over the New Orleans Saints on Sunday.

Rookie David Wilson picked up the load, rushing for 100 yards and two touchdowns, including a 52-yard score. Wilson -- who also earned NFC Special Teams Player of the Week for gaining 227 yards on four kickoff returns, including a 97-yard touchdown against the Saints -- is expected to start against Atlanta if Bradshaw is unable to play.

If Bradshaw is unable to go, Wilson may share carries with either Kregg Lumpkin or Ryan Torain.

"Just gave me more confidence that if need be, I could go in and be productive for my team because the season is narrowing down," Wilson said. "With Ahmad a little bit banged up, even if he is playing, they won't want to keep him in there and keep getting him banged up. It will be a rotation-type thing and having a successful game last week does give me confidence."

Defensive end Justin Tuck said he is confident in the rookie after seeing what he can do.

"Hey, man, that's one of the most impressive games I've seen, especially from a rookie who kind of got in the doghouse early," Tuck said of Wilson, who fumbled on his second pro carry against Dallas in the season opener. "To show that will to come back and continue to work and showcase that, without him we don't win that game on Sunday, hands down. We have to try our best now to keep his head the same size it is right now."

" Hopefully we get Ahmad back because that guy is a workhorse and the heart of our offense when he's healthy," Tuck added. "But if not we're going to need Wilson to step up. And whoever is behind to step up."

Bradshaw has battled through pain in his surgically repaired feet and ankles and often will play despite limited practice time during the week. He has missed only one game this season, during Week 3 against Carolina, because of a neck injury.

"The other day when he did injure the knee (against the Saints), he got it taped and went back in and had three straight short-yardage runs in a row to make a key first down," Coughlin said. "No one even knew what was going on there. He told me he had no limitations. He is a tough son of a gun. I say that with admiration."

Cornerback Prince Amukamara (hamstring) and safety Kenny Phillips (knee) also will not practice Wednesday, according to Coughlin.

Amukamara, the team's starter opposite Corey Webster, told Coughlin he is feeling better. But the coach described Amukamara's injury as "tricky."
