It is looking more and more likely that the Giants will have Prince Amukamara back on the field Sunday when they host Peyton Manning and the Broncos.
The cornerback went through a full practice with the team Friday after passing a battery of tests designed to see if he still was experiencing concussion symptoms.

Amukamara was injured when he collided with teammate Ryan Mundy on Sunday night while trying to make a tackle in the first half of the season-opening loss to the Cowboys.
Amukamara officially is listed as questionable, though Tom Coughlin was impressed with his practice and said he will play unless he unexpectedly suffers a relapse. Also listed as questionable is safety Antrel Rolle, who didn't practice after feeling soreness in his groin during practice Thursday.
Rolle said sitting out was just a precautionary move. "I'll be all right,'' he said. "I'll play come Sunday. It was better to be smart. Sunday is the most important thing.''
Amukamara had never suffered a concussion on the football field, but he said he did have one playing basketball when he was 10 years old.
"That one knocked me out,'' he said. "This wasn't like that. I saw a couple of flashes. Everyone said it looked like I had caught the Holy Ghost because my arms were out. It is definitely a scary feeling.''
Amukamara said he is mentally prepared to face Denver's potent passing attack. In the opener, Manning passed for seven touchdowns and 462 yards against the defending Super Bowl champion Ravens.
"I've been studying like crazy. I know this is a big week,'' Amukamara said. "Just being out there on the sidelines and catching those mental reps, those really go a long way.''
Notes & quotes: The Giants' running game may get some help because C David Baas (left knee) is listed as probable to make his season debut after going through a full practice. "Today, I thought I felt really well. It gave me a good indication that I'm going to play,'' Baas said. "The way [my knee] reacted when I did some things with power footwork versus running out on a screen, I'm feeling really good.'' . . . Backup RB Da'Rel Scott (knee) also is probable but rookie DE Damontre Moore (shoulder) is questionable . . . Despite two fumbles against Dallas, RB David Wilson still is listed as the starter on the depth chart, with Scott No. 2 and Michael Cox No. 3. The recently reacquired Brandon Jacobs was listed as "other.''
