Any cornerbacks available?

EAST RUTHERFORD, N.J. -- It appears the New York Giants might be without three cornerbacks on Sunday against the Philadelphia Eagles as Corey Webster (groin), Aaron Ross (back) and Jayron Hosley (hamstring) all were not practicing during the portion of practice open to the media on Friday. Webster and Hosley were in the bike area.

Hosley and Ross have not practiced all week, and Webster had a limited practice Wednesday before missing Thursday. If they can't go Sunday in what's essentially a must-win game, it leaves the team with just three cornerbacks in Prince Amukamara, Trumaine McBride and Terrell Thomas. The Giants could always make a move to bring Charles James up from the practice squad.

On the positive side for the Giants, defensive tackle Cullen Jenkins (knee/Achilles) was practicing after missing the previous two days. Jenkins said Thursday that Friday would be a big day for him in terms of getting the work in, but still expects he'll be a game-time decision against his former team.

Jenkins could be without his fellow starting defensive tackle Linval Joseph (ankle/knee) as he missed his third straight day of practice. If Joseph doesn't go, it opens the door for more playing time for second-round pick Johnathan Hankins. Hankins has been inactive for the first four games of his career.

Offensive guard Chris Snee (hip), center David Baas (neck), and tight end Adrien Robinson (foot) also were not practicing. Snee could possibly be put on season-ending IR on Friday, according to sources.

Offensive lineman David Diehl (thumb) was working for the third straight day.

There was also no sight of Jon Beason, who was scheduled to take a physical in the morning. The Giants are close to acquiring the Carolina linebacker, provided he can pass a physical. He could possibly replace Snee on the active roster.
