EUGENE — The last time Bob Chesney took the field at Autzen Stadium, he suffered a 51-34 defeat in the first round of the 2025 College Football Playoffs – what was a program-first appearance for James Madison.

So after taking his talents – alongside his top three coordinators and 11 of his players – to Westwood this past offseason, one could say there was a chip on much of the team’s shoulder entering the road affair.

But despite the victory, it did not come from a performance emblematic of a playoff contender – and what might be the country’s loudest stadium made it known.

Yet they got it done.

No. 21 UCLA football (5-0, 3-0 Big Ten) eked out a 17-15 win over No. 13 Oregon (3-2, 1-1) on Saturday afternoon in Eugene. The Bruins’ victory marks the squad’s first ranked victory since upsetting then-No. 7 Penn State in October 2025, as well as the Ducks’ lowest-scoring outing since September 2022. Chesney is now the first ever UCLA football coach to begin their Westwood tenure 5-0.

“Our guys did a really good job,” Chesney said. “Players did a great job on their conversations on the field. Our coaches did a great job preparing them for that. This week was a great week, a hard week of practice, coming off the bye. You’re back in school. All of a sudden, it’s 92, 93 (degrees) every single day we were down there on that field. These guys battled and fought and put themselves in a spot where they were ready to compete today.”

While the former Pac-12 matchup did not see the reunion of Oregon quarterback and former Bruin Dante Moore – who was ruled out with a concussion suffered against then-No. 12 USC on Sept. 26 – UCLA was met with another five-star quarterback in Dylan Raiola, who started his first game for the Ducks since transferring from Nebraska after two seasons.

The former Cornhusker’s performance was eerily similar to the last time he faced the blue and gold in his freshman season in 2024, when the Bruins held him to just 177 passing yards on a 51.9% completion rate, while sacking him three times.

On Saturday, UCLA would only be able to do so once, while also notching seven tackles for loss. The Bruins consistently made Raiola scramble out of the pocket and make awry decisions on his feet, unable to convert a single third down in the game. Despite Oregon boasting a room with six triple-digit receivers, Raiola threw for just 43 yards on a 32% clip – the worst of his career – routinely being hurried by a defensive line that dominated the trenches.

“It was a big part of it, and we didn’t have to bring a whole lot more than the four,” Chesney said of the four-man rush. “At times, we did, obviously, to just keep increasing pressure, but our defensive ends, our defensive line, did a great job getting home and getting around this quarterback.”

The Bruins’ secondary also excelled in man coverage, preventing receivers from getting open on one-on-one matchups, intercepting Raiola twice and allowing just 199 total receiving yards. Senior defensive back Scooter Jackson was particularly effective manning up against both Dakorien Moore on the sideline and freshman Messiah Hampton – coming out of the slot in place of an injured Jeremiah McClellan.

And despite a defense that broke up six passes and forced four fumbles – nearly matching the squad’s total from its first four games  – the offense failed to capitalize, keeping the Ducks within striking distance all game behind stellar execution from both their own defense and special teams.

On UCLA’s first drive of the game, a 62-yard pass to senior wide receiver Aiden Mizell failed to translate into a touchdown after a strong red zone stand prevented the Bruins from running into the end zone – an area in which they have been otherwise potent all year.

And it was that four-man rush – spearheaded by Ducks defensive lineman A’Mauri Washington, who compiled two pass breakups and continuously broke through nose gaps to hurry the pocket – that blanketed Nico Iamaleava all game. The senior quarterback was forced into his worst performance of the year, finishing with 162 yards on 10-for-17 passing, including two interceptions and multiple tipped passes.

The Ducks’ ability to stuff the trenches also quieted a run game that has otherwise been a hallmark of the Bruins’ offense this season, holding the blue and gold to just 79 rushing yards on 22 carries in the first half. UCLA running backs were repeatedly unable to turn corners or hit breakaway speed against an Oregon unit that logged seven tackles for loss.

“Disappointed in the first half, to be honest with you,” Chesney said. “Just really disappointed with how many opportunities we left out there, but also the plays that we made. … We can’t put ourselves in those situations that we did, and that got this game really close at halftime.”

Oregon’s sole touchdown through more than 57 minutes of action came off of a tipped pass and eventual fumble recovery by defensive back Koi Perich, setting up a one-yard run and score by tailback Jordon Davison.

Although the Bruins had the opportunity to extend the lead beyond one possession on their final drive of the first half, Iamaleava’s second pick completely missed the mark in the end zone in deep coverage, eventually being caught by Perich.

So when Iamaleava was ruled out of the second half due to a late second-quarter hit, senior Ty Dieffenbach, who transferred from Cal Poly SLO this past offseason, made his first appearance for UCLA. With Dieffenbach under center, the Bruins turned to what they usually do with Iamaleava out: spoon-feed carries to senior running back Wayne Knight – who finished the game with 103 rushing yards and two total touchdowns – and line up multiple running backs at once as Dieffenbach attempted just six passes.

“The crowd can only do so much, but you can block it out,” Dieffenbach said. “Everyone blocks it out, so I’ve just been waiting for this moment. I’m ready.”

Knight would clinch the Bruins’ first touchdown of the match in the second quarter off a 35-yard Wildcat play to break away from the defense. And the nation’s leader in points per game would give UCLA its first multiple-possession lead at the start of the final frame off a nine-yard catch from a Dieffenbach play-action.

With Raiola subbed out heading into the fourth quarter, the Ducks would ride with third-stringer Brock Thomas for the game’s remainder, but Oregon and its stadium pulse never backed down, with its frontline standing tall and preventing the rushing spam from giving any sense of security.

Thomas would help lead consecutive scoring drives late in the game, first ending with a field goal after a failed red zone scoring opportunity, before finding Evan Stewart on the next possession for a deep 44-yard receiving touchdown on which the wide receiver evaded multiple defenders to make it a one-possession game again.

Lining up for two, the Bruins were called for a facemask penalty that afforded the Ducks a relocation to the half-yard line, but it was the strong defensive line once again that stopped Oregon in its tracks – preventing a tied game entering the final two minutes of the game.

“We’re seeing a little tight formation,” said senior linebacker Sammy Omosigho. “We know it’s going to be a downhill run. They got the penalty, so it’s a short-yardage play. We know who’s going to run the ball. Who’s going to stop who? … Play the ball.”

With under 50 seconds left, the Bruins rallied to force three incompletions, running out the clock to survive a last-second catch from Stewart – inflicting revenge, which, while ugly, was revenge no less.
