Amukamara not practicing Wednesday

EAST RUTHERFORD, N.J. -- New York Giants cornerback Prince Amukamara, who left Sunday night's game with a concussion, will not practice with the team Wednesday, coach Tom Coughlin said.

"He does feel pretty good," Coughlin said Wednesday morning. "But he's got to follow the protocol."

The NFL's concussion rules require a player to pass a series of tests, conducted throughout the week, before he can be cleared to practice or play in a game. Amukamara, to this point, has not received medical clearance to return to practice. That doesn't rule him out for Sunday's game against the Broncos, but it does keep his status for that game in question until he is medically cleared. That could happen Thursday or Friday, but since all concussion cases are different, there's no way to predict.

If Amukamara can't play, Aaron Ross would likely start at cornerback opposite Corey Webster. Terrell Thomas played the slot cornerback position exclusively Sunday night against Dallas' Miles Austin and likely would handle those duties again, this time with another tough matchup against Denver's Wes Welker. The Giants prefer to keep Thomas, who missed the 2011 and 2012 seasons due to multiple knee surgeries, in the position he played throughout the offseason.

The Giants' secondary is already banged-up due to the loss of starting safety Stevie Brown to a torn ACL in the preseason. Against a high-powered Broncos passing attack that features Welker, Demaryius Thomas, Eric Decker and breakout tight end Julius Thomas catching passes from Peyton Manning, they need to have as many of their starters as possible. Losing Amukamara for this game would be a serious problem.

Also listed on the team's pre-practice injury report Wednesday were center David Baas (knee), linebacker Dan Connor (neck), tackle David Diehl (thumb), defensive end Damontre Moore (shoulder) and tight end Adrien Robinson (foot). All but Connor missed Sunday's game, and Connor left that game in the second quarter with the neck injury. Coughlin said Connor's injury was a concern because the team only has five linebackers on the roster. He said they could conceivably go with four in this game, but they did sign linebacker Emmanuel Acho to the practice squad Wednesday morning as well.

Baas, who has been out several weeks with a knee injury, was working with the first-team offensive line during the early portion of practice -- a good sign for his progress and his chances of playing again soon.

Defensive tackle Cullen Jenkins, who left Sunday's game with a fake injury to an unspecified body part, was not listed on the pre-practice injury report. Neither were defensive end Jason Pierre-Paul and fullback Henry Hynoski, who played in a limited capacity Sunday and are likely to get more to do this week.
