Vince Young was looking good while taking the start for the Eagles in their preseason finale Thursday night, completing 15 of 23 passes for 193 yards and a touchdown to make his claim as Michael Vick’s backup while holding off Mike Kafka.

But while rolling out to take a pass on a fourth-and-one late in the second quarter, he injured his right hamstring and is out for the game.

It’s unclear how serious the injury is, but as the Philadelphia Daily News pointed out, Young didn’t appear to be limping on his way to the locker room at halftime.

Kafka replaced him, and he proceeded to get rocked by the Jets defense, leaving some to wonder if backup-backup quarterback Jason Avant, who is a receiver during the day, would have to take over. But for now, Kafka is still in the game.

UPDATED (10:45 p.m. ET): After the game, coach Andy Reid told the media that Young suffered a strained hamstring and will undergo an MRI on Friday.
