EAST RUTHERFORD, N.J. -- The New York Giants' offensive line got some good injury news Thursday. Its secondary did not.
Starting cornerback Prince Amukamara, who suffered a concussion Sunday night in the season opener in Dallas, still was not cleared to practice Thursday and is in danger of missing Sunday's home opener against the Denver Broncos. Giants coach Tom Coughlin said that, if Amukamara is able to practice Friday and gets a full day of work in, he'd likely be OK to play Sunday. But Amukamara still needs to follow the NFL's concussion protocol and pass the appropriate tests before he's allowed to practice and/or play.
If Amukamara can't go, defensive coordinator Perry Fewell said, it "would be a really big blow" to a Giants' defense that will need all the help it can get against Peyton Manning and the Broncos' passing attack. Aaron Ross would likely take Amukamara's place as the starting corner opposite Corey Webster, with Terrell Thomas manning the same slot cornerback role he played in Dallas and throughout the summer.
As for the line, center David Baas was listed as a "limited" participant in practice, but he said his injured knee is feeling much better and that he's planning to be able to play Sunday.
"My plan is to be out there," Baas said. "As long as everything keeps feeling good, I should be fine."
Baas sprained his knee in the preseason game against the Colts and hasn't played since. His return would allow Kevin Boothe to move back over to left guard and send James Brewer back to his reserve lineman role.
In other Giants injury news:
Linebacker Dan Connor remained out of practice with a neck injury and seems unlikely to play. That would elevate Mark Herzlich to starting middle linebacker leave the Giants with only four linebackers, which may be fine since they expect to be playing a lot of nickel defense anyway against the Broncos' three-receiver sets.
Running back Da'Rel Scott, who injured his knee in Wednesday's practice and had an MRI, was a full participant Thursday and appears fine.
Defensive end Damontre Moore, who's been dealing with a pesky shoulder injury and hasn't played since the first preseason game, was a limited participant in practice.
