Ahmad Bradshaw is officially out of tomorrow's game against the Falcons in Atlanta, which means David Wilson officially is a starter in the Giants' backfield.

"It does change your mindset, now that you know, now that it's official," Wilson said Friday after practice. "It's like, 'All right, let's go play football.' "

Wilson also made some news of his own, declaring his backflip touchdown celebration a thing of the past. Everyone from general manager Jerry Reese on down to teammate Justin Tuck admonished Wilson for the backflips, and he told ESPN he is moving on from them.

"I think I'll let that celebration go for the rest of the season," he said. "I think it's for the team's best interest. I don't want to make anyone nervous, or upset, or scared. I want to do something that people enjoy."

Wilson did plenty of things that Giants fans enjoyed last Sunday. He had a breakout game with a 97-yard kickoff return for a touchdown, rushing TDs of 52 and 6 yards, 100 rushing yards on 13 carries and 227 yards on four kickoff returns.

Tom Coughlin said he has no plans to take Wilson off kick-return duty even though he will be the main ballcarrier. His backups will be Kregg Lumpkin and Ryan Torain, both of whom have been Giants for less than three weeks.

"I'm not taking him out of that," Coughlin said. "Last week with the plus-49-yard-line field position for the day, it was quite a bit different than the minus-15 the week before."

Bradshaw sat out practice for a third straight day with the left knee sprain he suffered against the Saints, and Coughlin said it was a fairly easy medical decision to declare him out.

"I'm sure he'd be disappointed right now," Coughlin said. "He thinks come game day it's all going to straighten out for him. In this case, it's, medically, really the only wise move."

And now the running game is all on Wilson's shoulders. That might give him more latitude regarding ball security -- he fumbled in the season opener on his second carry and didn't see a snap for weeks -- but he said he doesn't want it.

"I'm not looking for no leeway from mistakes," Wilson said. "I kind of like the way the coaches handled it; it showed me how much importance there is on that. I definitely don't want that to happen again, or even that thought to come across."

Notes & quotes: Cornerback Prince Amukamara (hamstring) was ruled out, along with safety Kenny Phillips (knee) and safety Tyler Sash (hamstring). Linebacker Michael Boley (back) is listed as questionable, but Coughlin thinks he will be ready.
