Agent: Giants' Jim Sorgi out 2-3 weeks

ALBANY, N.Y. -- As it turns out, Rex Ryan's Jets injured two New York Giants quarterbacks.

Backup quarterback Jim Sorgi has a torn capsule in his right throwing shoulder and will be out two to three weeks, his agent, Matt Brei, said on Thursday. Sorgi will join Eli Manning, who has 12 stitches on his head from the game against the Jets, on the sideline for Saturday's game against the Steelers.

Sorgi underwent an MRI at the Hospital for Special Surgery and was told by doctors that the injury is not related to the partially torn labrum he has dealt with in the past. Tendinitis from the partially torn labrum forced him onto the injured reserve last season with the Colts.

Sorgi's injury was first reported by the Newark Star-Ledger.

Sorgi could miss the remainder of the preseason because of the hit he absorbed from Jets linebacker Lance Laury, who blasted the backup quarterback a second after he delivered his second touchdown pass to Victor Cruz on Monday night.

This happened after Manning suffered a 3-inch gash on his forehead after being drilled by Jets linebacker Calvin Pace, losing his helmet and hitting his head on Jets safety Jim Leonhard's facemask.

With their top two quarterbacks out, the Giants were forced to practice with just one healthy quarterback, third-stringer Rhett Bomar. Head coach Tom Coughlin said it was the first time he had ever had to practice with only one quarterback.

The Giants signed rookie free agent Dominic Randolph on Wednesday night and released injured tight end Jake Ballard. Randolph was in the Giants' rookie minicamp in May before being released.

Bomar, a second-year pro who was a practice-squad player as a rookie, expects to see the majority of the action Saturday against the Steelers.

Though Manning feels well enough to practice, he won't be able to fully return until he can wear a helmet without impacting his wound.
