Bennett Jackson, the second-year safety who has been standing out for the New York Giants during training camp, missed Saturday's practice. Coach Tom Coughlin said after practice that Jackson is "unlikely" to make the trip to Cincinnati for joint practices and the first preseason game vs. the Cincinnati Bengals.

Jackson, drafted in the sixth round a year ago as a cornerback, missed all of 2014 after underdoing microfracture knee surgery. The Giants converted him to safety, and he has been working with the first team alongside second-round pick Landon Collins.

Jackson has drawn praise from safeties coach Dave Merritt.

"This kid, when he sees the ball — it's simple: see ball, get ball. When that kid sees the ball, he goes and gets the ball. This kid's ability to put his toe in the ground and go and burst out of his break, you guys see it out here, he's able to make plays," Merritt said earlier in the week. "He's making production and production, as Spags has said over and over, production is at the ball. This kid is able to get his hands on a couple of balls and passes already here. By far, more than any other safety I've had in camp so far."

The Giants are already working without Nat Berhe, second-year safety who is out for an undertermined length of time with a calf strain.

"Precaution, precaution," head coach Tom coughlin said after practice. "They don't want him to do any more damage, and he is sore, you can tell he was favoring it a little bit."

There was good news. Center Weston Richburg (cortisone shot in left knee) and left tackle Ereck Flowers (hip flexor) were practicing.
