The Giants now will look for a veteran backup quarterback and see who is released this week when teams cut their rosters down to 53 by Saturday. They have young and inexperienced quarterbacks Rhett Bomar and Dominic Randolph behind Eli Manning.
Sorgi tore the capsule in his right throwing shoulder when he was hit after a touchdown pass on Aug. 16 against the Jets. The initial prognosis was that he would be out two to three weeks, but Sorgi said Monday that his most recent visit with doctors revealed that his shoulder wasn't improving as fast as they had hoped.
Sorgi had hoped to practice Monday and play in Thursday's preseason finale against the New England Patriots, but he still wasn't able to throw. Sorgi said he will consider surgery if the shoulder isn't healed in a month or so.
Head coach Tom Coughlin said he thinks Sorgi will need surgery on his shoulder.
"I'd like him to get healed and get himself healthy so that may require that," Coughlin said.
Moss underwent surgery Tuesday morning to repair a sports hernia. He has been out for much of the preseason with a groin injury. He went to Philadelphia on Monday to have it examined, and stayed there for the surgery.
The fifth-year wide receiver was hoping to gain some playing time this season by winning the punt-returning job. But Moss, who has played in only 37 games in his previous four seasons, couldn't stay healthy.
"All I know is that the surgery and the rehab and those types of things, when would the athlete be able to return to full speed action and that type of thing ... it's very very difficult to operate like that," Coughlin said.
The Giants also placed rookie linebacker Adrian Tracy on IR. Tracy, the team's sixth-round pick, underwent surgery to repair ligament damage he suffered after dislocating his elbow against the Ravens on Saturday in Baltimore.
Offensive lineman Kevin Boothe was moved from the physically unable to perform list to the reserve-physically unable to perform list with a pectoral injury. That will keep Boothe out for at least the first six weeks of the season.
The Giants also released wide receiver Nyan Boateng to reduce their roster to 75 for Tuesday's deadline.
