1 DAY AGO • Associated Press

Efficient in victory Dieffenbach completed 18 of 31 passes for 198 yards and one touchdown during Saturday's 28-10 victory over Michigan State. He also had five rushes for 17 yards.

Impact Dieffenbach turned in a steady effort in Saturday's 28-10 win over Michigan State, throwing for 198 yards and a touchdown in his second straight start. Dieffenbach has kept unbeaten UCLA rolling without much drama after losing Nico Iamaleava (leg) for the year. A non-conference date with Nevada should help build confidence before the Bruins return to Big Ten play at Minnesota.

Returns for UCLA game Dieffenbach (leg) started the third quarter for UCLA after being examined in the medical tent and leaving the first half early, per Ben Bloch of the California Post.

Impact Diffenbach left the Bruins' clash with Michigan State early in the first half, heading to the medical tent and walking gingerly to the locker room. However, the gunslinger is back out on the field to start the third quarter; his leg appears to be just fine.

Exits Michigan State game Diffenbach (leg) left the first half early in UCLA's tilt with Michigan State in Week 8, per Connor Morrissette of 247Sports.com.

Impact Dieffenbach had completed 10-of-19 passes for 84 yards before he was knocked out of the game with an apparent left leg injury, per Chris Vannini of The Athletic. He reportedly walked very gingerly into the locker room after an extended stay in the medical tent. If the backup can't go, UCLA figures to turn to Madden Iamaleava at gunslinger.

Excels in narrow win Dieffenbach was 22-for-33 passing for 264 yards and one interception during Saturday's 17-7 win against Wisconsin. He also had six rushes for -12 yards.

Impact Dieffenbach's insertion into the starting role is actually a boon for UCLA's receivers, as he is more of a traditional passer than Nico Iamaleava (OFS), and he should provide great balance for the offense moving forward.

UCLA coach Bob Chesney: 'Serious concern' QB Nico Iamaleava could miss season

UCLA coach Bob Chesney says there's “serious concern” that quarterback Nico Iamaleava could miss the rest of the season with a knee injury

OCTOBER 13 • Associated Press

Looks poised to assume QB1 role for UCLA Dieffenbach looks set to assume the starting quarterback gig for UCLA in the wake of Nico Iamaleava's (knee) season-ending injury, first reported by Matt Zenitz of CBSSports.com.

Impact Dieffenbach took over for the injured Iamaleava in the second half of UCLA's upset win over Oregon, tossing for 43 yards on 3-of-6 passing. With news that the latter is expected to miss the remainder of the season with a knee injury, Dieffenbach is the logical replacement over Madden Iamaleava given his experience. Last season at FCS Cal Poly, Dieffenbach tossed for 1,305 yards, nine touchdowns and nine interceptions, adding 321 rushing yards and four scores on the ground.

OCTOBER 10 • Associated Press

Upgraded to available Dieffenbach (undisclosed) has been upgraded to available for Saturday's game against Purdue.

Impact Dieffenbach hasn't played this season, but he's cleared to do so and should compete for the Bruins' QB2 role behind Nico Iamaleava, with Madden Iamaleava as his competition. Dieffenbach last played for Cal Poly in the 2025 season, completing 92 of 162 passes for 1,305 yards and a 9:9 TD:INT.

SEPTEMBER 16 • ROTOWIRE

Still limited in practice Dieffenbach (undisclosed) continues to be limited in preseason practice, David Woods of On3.com reports.

Impact Even though Dieffenbach recently stepped onto the practice field, his purpose was to get loose on easy items like handoffs and short passes. The quarterback's injury status does not look like it has really improved, so with just over a week before UCLA's regular-season opener, he will remain questionable. Dieffenbach is competing against Madden Iamaleava for second-choice snaps, so if Nico Iamaleava were to go down, the injured signal-caller being QB2 would be crucial going into this season.

AUGUST 28 • ROTOWIRE

Limited in Monday's practice Dieffenbach (undisclosed) was limited in Monday's practice, Connor Morrissette of 247Sports.com reports.

Impact As expected, Dieffenbach has transferred colleges from Cal Poly to UCLA after his January commitment. It is unclear what the quarterback is dealing with, but given his recent development, he is questionable for UCLA's regular-season opener Sept. 5 at California.

AUGUST 17 • ROTOWIRE

Headed to UCLA Dieffenbach has committed to UCLA, Chris Hummer of 247Sports.com reports.

Impact Dieffenbach transferred from Pitt to Cal Poly ahead of the 2025 season, and he appeared in nine games with his new school. During those nine contests, he completed 92 of his 162 passes for 1,305 yards, nine touchdowns and nine interceptions. Dieffenbach also added 321 rushing yards and four rushing scores. He'll be a reserve option for the Bruins.
