Drew Allar passed for three touchdowns and Tyler Warren found the end zone twice as No. 4 Penn State rolled over host Purdue 49-10 on Saturday in West Lafayette, Ind.

Allar finished with more touchdowns than incompletions, as he went 17 of 19 for 247 yards without a turnover for the Nittany Lions (9-1, 6-1 Big Ten). Warren totaled eight catches for 127 yards and a score and also had a 48-yard scoring run.

Hudson Card passed for 151 yards and Max Klare had 91 receiving yards and a touchdown for Purdue (1-9, 0-7), which has not won since Week 1 and has not beaten Penn State since 2004. The Boilermakers have faced three top-five opponents in the last month, losing those games by a combined margin of 129-10.

The Nittany Lions wasted no time featuring the Allar-to-Warren connection. The two hooked up for gains of 15, 17 and 27 yards on the opening drive of the game, setting up Allar’s 2-yard scoring strike to Kaytron Allen.

On the next Penn State trip, Allar found Warren for 9 yards on third-and-2 early on the drive. The march ended with Allar’s 15-yard touchdown pass to Warren, making it 14-0.

The Boilermakers got on the board with a field goal midway through the second quarter, but the ensuing possession featured a backwards pass from Warren to Allar, who then threw back across the field to Warren for a 38-yard gain. Nicholas Singleton plunged in for a 10-yard score on the next play, making it 21-3.

That was still the score at halftime before the visitors erupted for three touchdowns in the third quarter — all covering 40-plus yards.

First, Warren took a direct snap and went 48 yards for a touchdown. Then Allar found a wide-open Harrison Wallace III in the end zone for a 46-yard score. And finally, backup QB Beau Pribula kept the ball on a read-option and sprinted 49 yards to make it 42-3.

Purdue’s only touchdown came midway through the fourth, when backup quarterback Ryan Browne found Klare for a 20-yard score.
