Nat Berhe's stop-and-go season has stopped again. Perhaps for good.

The second-year safety reinjured his calf after only one day of full practice, Tom Coughlin said on Thursday, and he'll have surgery to remove a hardened blood clot. He most likely will be placed on injured reserve when the team trims its roster to 75 on Monday.

Prince ready

Cornerback Prince Amukamara will make his preseason debut Saturday night after missing the first two games with a groin injury.

"I think preseason games are important because you get your body in shape and you start to work that muscle memory," he said. "And going against players from a different team [is beneficial]. So I'm excited I get to play this week."

He also said he believes his groin injury is behind him.

"I feel like I'm completely over it," he said. "I've been full-go, not limited in any reps. I've been able to do everything that I did before I got injured. So I wouldn't say I'm limited in any way."Giant steps

Coughlin said WR Victor Cruz (calf) will not play against the Jets and S Landon Collins (knee) will . . . LB Mark Herzlich (concussion) had been making progress, Coughlin said, but he did not feel well on Wednesday afternoon, delaying his return . . . CB Jayron Hosley (concussion) returned to practice this week and will play. The Giants liked how Hosley played before his injury in the preseason opener. "We'd like to see him do some more things," Coughlin said. "There's a bunch of them we'd like to see do some more things."
