The New York Giants believe Daniel Jones suffered a "pretty bad" hamstring injury in Sunday's win against the Cincinnati Bengals.
The Giants are currently in first place in the NFC East despite a 4-7 record and no wins against a team with a winning record.
Jones was injured at the end of a 7-yard run early in the third quarter. He briefly reached for the back of his right leg while on the ground, but remained in the game.
