Penn State outgained Purdue 422 yards to 241 and had a shutout until the middle of the fourth quarter.

Linebackers Josh Hull and Navorro Bowman led the way. Hull had 11 tackles, including two for losses, and Bowman had nine tackles, with two for losses.

Freshman safety Drew Astorino intercepted a pass and returned it 29 yards.
