The teams were tied at 10 after regulation, exchanged field goals in the first two overtimes, then began to alternate 2-point attempts in the third OT as part of a format tweaked ahead of the 2021 season.
The 2-point conversion shootout started in 2019, the season after LSU and Texas A&M played a seven-overtime game that left both teams badly beaten up. The rule was tweaked this year, with the 2-point conversion possessions beginning with the third overtime instead of the fifth.
The Illini (3-5, 2-3 Big Ten) outgained the Nittany Lions 370 yards to 207 in regulation and battled back from an early 10-0 deficit.
Peters, normally Illinois’ starter, came off the bench when Artur Sitkowski hurt his left hand in the sixth overtime period.
Led by Chase Brown’s 229 total yards, the Illini tied it 10-10 early in the fourth quarter with a 37-yard field goal from James McCourt.
A sloppy fourth quarter gave way to overtime, where McCourt and Stout matched each other on field goals before a string of goal-line standoffs pushed the game into unprecedented territory.
