Raiders rookie quarterback Fernando Mendoza showcased flashes of potential in his preseason debut, completing 10 of 16 passes for 97 yards and a touchdown during four drives in a 27-14 loss to the Arizona Cardinals. Despite moments of adjustment to the NFL's speed, Mendoza demonstrated why the Raiders trust him as their future. Coach Klint Kubiak described him as an "ascending player," noting significant development.

Mendoza's touchdown pass to wide receiver Jack Bech tied the score at 14 in the second quarter. While acknowledging areas for improvement, such as timing and anticipation, Mendoza remained focused on learning from the experience. His performance marked him as the first No. 1 pick since Baker Mayfield in 2018 to throw a touchdown pass in his preseason debut.

Despite Mendoza's promising outing, Kubiak reaffirmed that veteran Kirk Cousins remains the starting quarterback for Week 1. Mendoza expressed surprise at the speed of NFL defenders and the newfound autonomy of professional players compared to college.
