Today apparently was a dangerous day to be a pass-catcher of any kind. While Mario Manningham and his sore groin did return to make a 60-yard grab, Steve Smith pulled out of practice early because of an apparent groin injury. So, too, did rookie TE Jake Ballard with a hamstring. And shortly after those two left, rookie WR Duke Calhoun was walked off the field with an unknown injury.
Meanwhile, looks like the eminent Guy Whimper has taken the injured Rich Seubert's place at left guard. Probably should expect to see him in there, since fifth-round guard Mitch Petrus is getting work behind Chris Snee on the right side. Make your own conclusions, but I would think the gut feeling on Whimper would be "Hurry back, Seubert!"
Also, the Giants waived WR Adam Jennings, who some people on this blog seemed to be high on as a potential kick returner, and signed WR Nyan Boateng from Cal.
