USC nearly came away with the road win over Illinois, but the Trojans left too much time on the clock after taking the lead on a 16-yard touchdown pass from quarterback Jayden Maiava to receiver Makai Lemon.

With 1:55 left in the game, Illinois' offense drove down the field and set up a game-winning field goal for David Olano, who drilled the 41-yard kick.

Then-No. 24 TCU lost to Arizona State, and the Sun Devils are now ranked No. 25 after the upset win while the Horned Frogs are unranked.
