The New York Giants lost quarterback J.J. McCarthy to an apparent injury in the third quarter of his second start with the team.

McCarthy's injury occurred when he was scrambling to his left on a designed quarterback run. The 23-year-old quarterback was hit hard in the midsection by Philadelphia Eagles linebacker Zack Baun at the end of his run, and he remained on the ground in pain following the play.

McCarthy was able to get to the sideline but appeared to be in a lot of pain. He was captured by the broadcast trying to throw passes, but he collapsed to the ground and grabbed at his right side after attempting a throw.

He was then taken into the blue medical tent for further evaluation following his brief throwing session. He was then seen jogging to the locker room, with athletic training staff in tow for the team.

Here's what to know about McCarthy's injury.
