PRINCETON, N.J. (AP) -- Sedale Threatt Jr. never had to move the Lehigh University offense more than 51 yards against Princeton thanks to opportunistic defense and special teams.
Lehigh recovered a fumble on Princeton's first play from scrimmage, one of six turnovers it took advantage of in a 32-21 win Saturday night.
Threatt passed for one touchdown and ran for another to lead Lehigh to a 23-0 halftime lead.
The Mountain Hawks (1-1) recovered a Princeton fumble, intercepted two passes, fell on a muffed punt and a picked up a live kickoff in the first half as Princeton battled first-game jitters.
After Lehigh blocked a punt out of the end zone for a safety to open the second half scoring, Princeton (0-1) responded with a pair of 86-yard touchdown drives to make it a two-score game.
Bill Foran's first career touchdown pass went to Rob Toresco. He hit Adam Berry for a 15-yard score to cut Lehigh's lead to 25-14 by the end of the third quarter.
Lehigh took a 32-14 lead on a 2-yard run by Jaren Walker to start the fourth quarter, and Brannan Thomas recorded his second interception of the game.
Back-up Princeton quarterback Greg Mroz's 21-yard touchdown pass to Will Thanheiser accounted for their final score.
It was the eighth win in the last nine meetings of the series for Lehigh, which won their first game over an Ivy League team under second-year coach Andy Coen. It was the first time in five years that Princeton lost its season opener.
