Canty will be available to play for the first time since the Giants' Super Bowl victory over the New England Patriots.
The Giants placed running back Da'Rel Scott on injured reserve to make room for Canty. Scott had surgery to help repair his right meniscus earlier this week.
"He's in outstanding shape condition-wise," Giants coach Tom Coughlin said Friday. "He hasn't been hit, obviously. We'll come up with the right formula."
The Giants may ease Canty back in. They definitely can use Canty with Rocky Bernard (quadriceps) missing a third straight game.
"I always feel I can help this team and contribute in some fashion, so from that perspective, I feel like I would be an asset," Canty said earlier this week.
Canty had offseason surgery on his knee and sat out training camp and the first six games on the PUP list. Tight end Travis Beckum, who tore his ACL during the Super Bowl, hopes to start practicing next week and come off the PUP list soon.
"You still got to be smart about this thing because he is back doesn't mean we are just going to throw him in there," defensive end Justin Tuck said of Canty. "We are going to be smart and he is going to be smart. At the end of the day, it is all about being ready for the long haul and we don't want to send him out there and he is not absolutely ready yet."
But Tuck says Canty's size and length will be a much-welcomed addition to the defensive front.
"You ask quarterbacks if they want to see a 6-foot-7, 300-plus pound guy right in the middle of their face with arms that look like branches," Tuck said. "You might want to check out the quote from Tom Brady in the Super Bowl -- it is not fun -- about our D-line in general.
"If you can't get the quarterback, get your hands and knock down passes," Tuck added. "Especially him and (Jason Pierre-Paul) with those go-go gadget arms."
