UCLA Quarterback Nico Iamaleava Out for the Season Due to Knee Injury

UCLA’s senior starting quarterback, Nico Iamaleava, will miss the remainder of the season following a knee injury. This development affects the No. 12 Bruins who have begun coach Bob Chesney’s first season with a 5-0 record. The team appears to have a favorable chance at a College Football Playoff spot.

The injury occurred during the first half of UCLA’s victory over Oregon. Iamaleava was running with the ball when he was spun around and tackled, grabbing his leg as Oregon’s Bear Alexander hit his head. He returned for a single play before halftime, with Chesney stating during a TV interview that Iamaleava was fine after a quad hit. However, after halftime, Iamaleava did not rejoin the team and was later seen in street clothes.

Iamaleava completed 10 of 17 passes for 162 yards with two interceptions before exiting. Over their first five games, he amassed 982 passing yards, 144 rushing yards, five total touchdowns, and four interceptions. Chesney initially believed Iamaleava’s injury was a thigh issue, but a full medical evaluation suggested it might be more serious.

Dieffenbach Steps Up

Senior quarterback Ty Dieffenbach, previously third on the depth chart, led the Bruins’ offense during the second half. He managed to complete three passes for 43 yards and a touchdown, contributing to their 17-15 win. Chesney commented on Dieffenbach’s performance, acknowledging his ability to step up when needed.

Madden Iamaleava, Nico’s younger brother, played two games this season, taking control of the offense against Purdue and Maryland. The decision to entrust Dieffenbach with the game against Oregon centered on his ground game threat. Chesney explained their approach was week-to-week, based on practice performances.

Dieffenbach noted that the competition for the UCLA backup spot is ongoing. He emphasized the consistency required in practice, sharing that both he and Madden execute their roles effectively. Dieffenbach’s leadership during the Oregon game marked his first major impact since joining UCLA.

Before playing for UCLA, Dieffenbach spent 2025 at Cal Poly, where he started 11 games. During that season, he recorded 1,305 passing yards, nine touchdowns, nine interceptions, 321 rushing yards, and four additional scores. Prior to Cal Poly, he spent two years at Pittsburgh without game action. Originally from Agoura High in Southern California, he was a wide receiver before amassing 4,153 passing yards and 48 touchdowns during his high school varsity career.
