Team doctors examined Keller after he was seen grabbing his hamstring following a 24-yard reception from quarterback Mark Sanchez on the team's opening drive.
UPDATE: More bad luck for the Jets. Reserve tight end Josh Baker went down clutching his right knee midway through the second quarter. Baker was injured attempting to haul in a Sanchez pass in Carolina's end zone. He was undercut on the play by Panthers cornerback Josh Norman. Trainers helped Baker off the field, leaving the Jets paper-thin at the position.
