Backup Steps Up to Keep Bruins Unbeaten

By the Editorial Team · Sunday, October 18, 2026

UCLA defeated Wisconsin 17-7 at the Rose Bowl, improving to 6-0 and becoming bowl eligible with backup quarterback Ty Dieffenbach leading a key late scoring drive in his first FBS start. The Bruins' resilient defense held Wisconsin to just 214 total yards, securing the victory despite a limited running game and solid efforts from Wisconsin's mobile quarterback.

UCLA secured a 17-7 victory over Wisconsin on Saturday at the Rose Bowl, remaining undefeated at 6-0 under coach Bob Chesney and clinching bowl eligibility. The No. 12 Bruins, who are the only unbeaten team in the Big Ten, relied heavily on backup quarterback Ty Dieffenbach in his first FBS start following an injury to starter Nico Iamaleava.

Dieffenbach, a former Agoura High standout, completed 22 of 33 passes for 264 yards, narrowly missing Iamaleava’s career-best single-game yardage by 12 yards. Despite expectations being modest due to the abrupt role change, he demonstrated poise and efficiency, especially on critical third-down conversions, completing 13 out of 20 attempts. His most notable contribution came in the fourth quarter with a six-play, 89-yard drive that ended with Anthony Woods’ three-yard touchdown run, extending UCLA’s lead to 17-7 and helping seal the win.

UCLA’s offense had struggled to establish a strong running game, managing only 3.2 yards per carry against Wisconsin’s defense, which had been ranked 15th nationally in total defense and ninth in passing yards allowed prior to the game. Heisman Trophy candidate Wayne Knight was held to 29 all-purpose yards but managed to score his 12th touchdown of the season.

Wisconsin’s defense contained UCLA’s “Bruin Bullies” at the line of scrimmage, particularly limiting the effectiveness of the Bruins’ ground game. However, Wisconsin quarterback Colton Joseph posed a threat with his mobility, rushing for 71 yards and a touchdown using varied formations to challenge UCLA’s defense. Despite this, UCLA’s defense held the Badgers to 214 total yards, including just 66 passing yards. Wisconsin’s leading receiver, Jaylon Domingeaux, was limited to 26 yards.

The Bruins’ defense showed resilience on crucial plays, including a 10-yard sack by linebacker Jalen Woods in the second quarter that forced a missed 46-yard field goal attempt by Wisconsin kicker Gavin Lahm. UCLA’s secondary, missing starting outside cornerback Rodrick Pleasant, effectively blanketed their opponents, preventing Wisconsin from gaining sustained momentum in the passing game.

Wisconsin managed only one touchdown and was denied a chance to take the lead late in the game after UCLA forced a punt following strong defensive stops. In the fourth quarter, the Bruins stopped running back Darrion Dupree short on a fourth-and-two attempt at midfield, effectively ending Wisconsin’s comeback hopes.

Despite no takeaways for UCLA in the game, the Bruins’ combined offensive composure and timely defensive plays preserved their unblemished record through six games this season.
