Jim Sorgi had an MRI exam Thursday and was diagnosed with a torn capsule in his right shoulder that will sideline him two to three weeks, said Matt Brei, the quarterback's agent. The injury doesn't involve Sorgi's labrum, however, which was injured last season. Needing quarterback depth, the Giants signed free agent Dominic Randolph on Thursday and waived tight end Jake Ballard, who was sidelined most of training camp because of a hamstring injury. Eli Manning will miss this week's preseason game due to injury.
