DUBLIN -

Penn State won a thrilling season opener with a 36-yard field goal as time expired to defeat the University of Central Florida 26-24 in front of a raucous 55,000-strong crowd in Ireland.

Behind a comeback led by second-half replacement quarterback Justin Holman, the Knights appeared to have scored their own unlikely come-from-behind victory when Holman scored on a 6-yard touchdown run to put UCF up 24-23 with 1:13 left.

But Christian Hackenberg coolly directed a seven-play drive to set up Sam Ficken's fourth successful field goal.

Penn State ended the first half up 10-3, but should have been ahead by more as UCF struggled to move the ball at all. Both teams looked jet-lagged in what was the first overseas game in either school's history.
