Ten and Oh in the Rain: Dieffenbach Returns From a Shoulder Scare and Scooter Jackson's Two Picks Keep No. 4 UCLA Perfect, 22-14

November football is supposed to be ugly, and Friday night in Pasadena delivered. In a steady rain at the Rose Bowl, No. 4 UCLA lost its quarterback to a shoulder injury, got him back, leaned on a ball-hawking defense and beat Illinois 22-14 to improve to 10-0 for the first time since 1998, the Los Angeles Times reported ^[1]. It is only the third 10-0 start in program history ^[2].

The Scare and the Return

The game turned on a hit late in the first half. Quarterback Ty Dieffenbach went down with a left shoulder injury after Illinois defensive lineman Carter Janki got to him, Yahoo Sports reported ^[4]. Third-string quarterback Madden Iamaleava took over and played the next three series while Dieffenbach stayed in the locker room ^[4].

That alone tells you how thin the Bruins have been stretched at the position. Dieffenbach only became the starter about a month ago, after Nico Iamaleava was injured, according to ClutchPoints ^[6]. Losing a second starting quarterback with a perfect season on the line would have been a crushing blow.

Instead, Dieffenbach came back with 55 seconds left in the third quarter ^[4]. On his first drive back, he completed all five of his passes and led a seven-play, 75-yard march that ended with a 26-yard touchdown throw, ESPN and Yahoo reported ^[3][4]. He finished 13 of 20 for 232 yards, two touchdowns and an interception, and he is now 5-0 as UCLA's starter ^[3][4].

Receiver Aidan Mizell again did damage, finishing with six catches for 176 yards and a touchdown ^[2].

Scooter Jackson's Night

If Dieffenbach supplied the courage, the defense supplied the wins column. UCLA intercepted Illinois three times, and Scooter Jackson had two of them ^[1][5]. His second pick came late in the fourth quarter, with Illinois pushing to tie. Jackson returned it 41 yards, setting up a short field goal that made it 22-14 with under three minutes to play ^[1][5]. It was his fifth interception of the season, the most in the conference ^[5].

The Bruins also got two points the hard way. Defensive lineman Aiden Gobaira sacked Illinois quarterback Katin Houser in the end zone for a safety ^[5]. On a rain-soaked night when the offense sputtered for long stretches, those plays were the difference.

From 3-9 to 10-0

It is hard to overstate how far this program has come in a single year. UCLA went 3-9 in 2025, then hired Bob Chesney after a successful run at James Madison ^[6]. ClutchPoints noted that Chesney has now led the Bruins to their best start of the 21st century ^[6].

The 1998 team, the last UCLA squad to open 10-0, was also the last to win a conference championship, the Times noted ^[1]. This group has two regular-season games left, against Michigan and rival USC ^[6], before any talk of championships can get serious.

McAllister's Take: Winning Ugly Is Still Winning

I have covered plenty of unbeaten teams that looked unbeatable in September and fell apart in November. What I like about this UCLA team is that it found a way on a night when almost nothing came easy.

Teams that win championships usually have a game like this somewhere on their schedule: bad weather, a key player hurt, a hungry opponent pushing late. The Bruins answered with a third-string quarterback who kept the ship steady, a starter who came back and went 5-for-5 on the drive that mattered, and a defense that took the ball away three times.

There is a lesson in that for young players, and for the rest of us. Toughness is not about avoiding hard nights. It is about showing up for your teammates when the hard night comes. Dieffenbach could have stayed in the locker room. He came back out in the rain.

Now the real test begins. Michigan and USC will bring everything they have, and the playoff committee will keep a close eye on every snap. If Dieffenbach's shoulder holds up and the defense keeps taking the ball away, the Bruins have a real chance to finish the regular season unbeaten.

For a fan base that waited 28 years for another 10-0 start, Friday night in the rain felt like more than a win. It felt like a program coming home.
