Trevone Boykin scored on a 1-yard TD run with 38 seconds left and TCU rallied to beat Iowa State 21-17 on Saturday and snap a three-game losing streak.
Boykin ran for three touchdowns for the Horned Frogs (4-6, 2-5 Big 12), who remain in contention for possible bowl eligibility with two games left.
The Horned Frogs went 58 yards in just 1:56 - a drive keyed by a 22-yard run from Aaron Green on 4th-down-and-1 - and took a four-point lead on their only score of the second half.
Grant Rohach threw for 148 yards for Iowa State (1-8, 0-6), whose last-ditch effort ended near midfield.
The Cyclones have lost six straight.
Casey Pachall threw for 245 yards for TCU.
