Young rolled out on a fourth-down play and was about to run for the first down when his right leg stuck in the turf. He wound up throwing an incomplete pass as he went down, then immediately limped to the sideline.
Eagles trainers looked at the back of his right knee and Young gimped along the sideline before heading to the locker room with 18 seconds remaining in the half. He did not come out to the sideline for the start of the second half, replaced by Mike Kafka.
The second-string quarterback to Michael Vick was 15 for 23 for 193 yards and one touchdown against New York's backups.
