Oftentimes when a starter is injured a team must turn to an unproven backup as a replacement and cross its fingers. If the Giants have to play without linebacker Devon Kennard for a few games because of his hamstring injury, they'll have the luxury of relying on a group of veterans to fill his roles.

"Guys have done everything," Mark Herzlich said Wednesday of the list of backups at linebacker that includes him, Jonathan Casillas and Jasper Brinkley. "We know what to do."

Tom Coughlin said he'll likely use all of them to replace Kennard, a second-year player emerging as the team's best playmaker on defense. In last Sunday's win over Buffalo, Kennard had an interception and batted a ball down at the line of scrimmage on a blitz.

"He's playing at an extremely dominating level," Jon Beason said, "and any time you lose a guy like that, it's tough."

Kennard did not practice on Wednesday, but he still held out hope that he could suit up Sunday night against the 49ers.

"I love the way that we're playing, I love what we have going on, and if there's any way possible I can play on Sunday, I will," Kennard said.

WR White added to 53

The Packers have the Giants' leading wide receiver from this preseason on their roster. Now the Giants have theirs.

Myles White, who led Green Bay with 16 receptions for 157 yards and two TDs this summer, was signed to the 53-man roster from the Giants' practice squad. White had been on the practice squad for three weeks ever since he was cut by the Packers so they could make room for James Jones, the veteran who spent the summer on the Giants' roster before he was cut.

"It's a funny situation," White said. "But I wish James the best and those guys the best. I hope they feel the same toward me."

Coughlin had no update on the status of Victor Cruz, who will most likely not play on Sunday . . . CB Jayron Hosley did some running on the side during practice despite suffering his second concussion of the season on Sunday. "He didn't think he'd even be restricted today," Coughlin said. "But you've got to go through [the protocol], you've got to go through it." . . . CB Trumaine McBride (groin) did not practice, but Coughlin said he expects him to be available today.
