Snee, Jacobs, Tuck unable to practice

EAST RUTHERFORD, N.J. -- Pro Bowl guard Chris Snee sat out practice Wednesday as he continues to recuperate from a concussion.

New York Giants coach Tom Coughlin said Snee and long snapper Zak DeOssie, who also missed practice due to a concussion, are feeling better. The two must be cleared by doctors and pass their baseline tests before being able to play against the Buffalo Bills on Sunday.

The Giants practiced without several key players. Defensive end Justin Tuck (neck/groin), running back Brandon Jacobs (knee), defensive end Osi Umenyiora (knee) and fullback Henry Hynoski (neck/burner) all did not practice on Wednesday.

Center David Baas, who missed Sunday's loss to Seattle with a neck/burner injury, and linebacker Michael Boley (knee) participated in a limited practice.

"Yeah, I felt good today," Baas said. "Went out there and participated in pretty much most of the practice. There was a few things that I had to make sure I kept my hat out of and just use my hands, but felt great and like I said, we'll just continue to evaluate it. ... Everything looks good so far."

If Snee is unable to play, Kevin Boothe could start at guard. Boothe started at center last week in place of Baas. In a move likely to add depth due to Snee's condition, the Giants added offensive lineman Selvish Capers and released quarterback Ryan Perrilloux off the team's practice squad.

Tuck's neck injury is basically being monitored on a daily basis. The defensive end has considered sitting out until after the Giants' bye week, which comes after this Sunday's game.

Cornerback Prince Amukamara officially did not practice; however, he did go through a light group special-teams punt coverage drill during the early portion of practice open to the media. This is the first time reporters have seen the team's first-round pick do a group drill.

"It felt good when I took off on the sideline, I had a little burst," said Amukamara, who has been out since early in training camp with a broken foot. "I didn't feel my foot there at all. The only time I feel my foot is when I am done doing everything. That is just sore, that is not pain."

"I think I'm still doing good on the timeline that Coach Coughlin said, which is I will probably be with the team after the bye," he added.

Umenyiora, who was on the field, likely was resting his surgically repaired knee.
