LINCOLN, Neb. -- No. 16 Nebraska produced its fourth double-digit comeback victory in Big Ten Conference play, using a quick start to the second half to rally for a 32-23 win over Penn State on Saturday.
Nebraska (8-2, 5-1) trailed 20-6 at halftime but scored two touchdowns within the first 5 1/2 minutes of the third quarter to quickly erase that deficit.

Nebraska tacked on a safety with 5:02 remaining, and Brett Maher kicked a 33-yard field goal with 23 seconds left, helping the Huskers maintain control atop the Big Ten's Legends Division with two games to play.

Nebraska went three-and-out, but Maher's 69-yard punt pinned Penn State at its 2-yard line. That set up an intentional grounding penalty when Cameron Meredith forced McGloin to throw out of the end zone for in a safety that gave Nebraska control.
