(AP Photo/Bill Kostroun) EAST RUTHERFORD, N.J. (AP) - New York Jets quarterback Mark Sanchez left the team's preseason game against the Giants late in the fourth quarter with what appeared to be a shoulder injury. Sanchez, in with the backup offense after Geno Smith played into the fourth quarter, rolled out under heavy pressure and completed a 23-yard pass to Mohamed Massaquoi before having his right shoulder slammed into by Marvin Austin with 5:40 left in the game. Sanchez stayed on the turf for a few moments as the team's trainers ran out to check on him. The quarterback got up on his own and flexed his right arm and hand as he headed to the sideline. He took one practice throw on the sideline and appeared to shake his head, as if to say, "No." Trainers took Sanchez's jersey and pads off on the sideline, and then wrapped his shoulder in ice before taking him to the locker room. The team had no immediate word on the nature or severity of Sanchez's injury.
