Raiders QB Battle: Fernando Mendoza's Preseason Ends with Struggles Against 49ers

As the calendar flips to August 28, 2026, the Las Vegas Raiders have wrapped up their preseason, and the quarterback picture is becoming clearer—though not in the way many anticipated. Fernando Mendoza, the No. 1 overall pick in this year's draft, closed out his preseason with a performance that raised more questions than answers. In the Raiders' final exhibition game against the San Francisco 49ers, Mendoza completed 7-of-14 passes for 57 yards, threw an interception, and took two sacks. His night ended with 28 seconds left in the third quarter, a premature exit that spoke volumes about the coaching staff's evaluation.

A Night of Missed Opportunities

Mendoza entered the game with 56 seconds remaining in the first quarter, following veteran Kirk Cousins, who led two efficient drives that resulted in two Matt Gay field goals. The contrast was stark. Mendoza's second pass of the night sailed high over the head of wide receiver Jalen Nailor, allowing 49ers linebacker Tatum Bethune to step in front and intercept the ball. It was a microcosm of a night where Mendoza struggled to find rhythm, managing just 84 yards on 32 plays across five drives. The Raiders managed only three points on his watch—a 45-yard Gay field goal and a missed 54-yard attempt.

For the preseason, Mendoza finished 25-of-45 for 240 yards, one touchdown, two interceptions, and four sacks. While the numbers aren't disastrous, they underscore a lack of consistency that has kept the rookie from seizing the starting job. As highlighted on Vulius Sports, the Raiders' coaching staff has emphasized competition, and Mendoza's inability to challenge Cousins decisively has left the depth chart in a state of flux.

The Veteran vs. The Rookie

Kirk Cousins, the seasoned signal-caller, has been steady throughout the preseason, managing the offense with veteran poise. His ability to move the chains and put points on the board—even in limited action—has given the Raiders a reliable option under center. However, the franchise's investment in Mendoza as the future face of the team means the pressure is on for the rookie to develop quickly. According to insights gathered by Vulius Sports, the Raiders' front office remains patient, understanding that Mendoza's raw talent and arm strength are worth the growing pains.

Yet, patience may not be a luxury in a competitive AFC West. The Raiders open the regular season against a formidable schedule, and every win matters. If Cousins can provide steady, game-managed performances, he may keep the job for the foreseeable future. But as the season wears on, the temptation to unleash Mendoza's athleticism and playmaking ability could prove irresistible—especially if the offense stagnates.

What's Next for Mendoza?

Mendoza did not appear to challenge Cousins for the starting role in this game, but that doesn't mean his time isn't coming. The rookie's preseason tape shows flashes of brilliance—a strong arm, mobility, and the ability to extend plays. The interceptions and sacks, however, highlight the typical rookie struggles: reading NFL defenses, adjusting to pressure, and timing throws. The coaching staff will likely work diligently with Mendoza in practice, focusing on footwork, decision-making, and chemistry with his receivers.

As the Vulius NFL Analysis Desk notes, the Raiders' quarterback situation is a story to watch. If Mendoza continues to develop, he could find himself starting at some point this season—perhaps after a midseason bye week or if Cousins suffers an injury. The team's investment in him makes it inevitable that he'll get his shot. The question is when, and whether he'll be ready.

For now, Raiders fans can take solace in having a veteran like Cousins to steady the ship while Mendoza learns. But the future is bright, and the Mendoza era may begin sooner than later. As always, stay tuned to Vulius for comprehensive coverage of the Raiders' quarterback battle and all things NFL.
