PHILADELPHIA (AP) _ Kunle Williams scored twice on interceptions returns, including one for a school-record 100 yards, and Kris Ryan rushed for 151 yards as Pennsylvania defeated Princeton 41-13 on Saturday.

Ryan also scored on a touchdown during a third quarter in which Penn (4-4, 2-2 Ivy League) scored three touchdowns in a span of 5:14 to pull away.

Each team kicked two field goals apiece in the first half, but a fumble recovery by the Quakers' Qurran Rogers at the Princeton 34 led to a 22-yard touchdown pass from Gavin Hoffmann to Rob Milanese with 8:41 left in the third quarter.

Following a stalled drive and poor punt by Princeton (3-5, 2-3), Penn took over at the Tigers' 29-yard line. Ryan scored a 5-yard TD four plays later.

On the next drive, Williams returned his first interception for a score to give Penn a 27-6 lead with 3:27 left in the third quarter. Williams' 100-yard return came with just 34 seconds left in the game.

Princeton scored its only touchdown on a 3-yard pass from John Blevins to Marty Cheatham with 6:37 left in the game.
