2026 Week 5 Fantasy Football Breaking News: Fernando Mendoza Makes Raiders Debut, Kirk Cousins Holds Starting Job — For Now

According to ProFootballTalk (NBC Sports), Fernando Mendoza — the first overall pick of the 2026 draft — made his regular season debut Sunday when he replaced Kirk Cousins late in a 45-17 blowout loss to the Patriots. Head coach Klint Kubiak said he wanted to give Mendoza "some exposure" and that there is no thought of a lasting change at quarterback right now. Mendoza finished 6-of-8 for 48 yards, did not score, and was stopped short of a first down on a fourth-down scramble.

Kubiak's "no lasting change" comment keeps Cousins as the starter on paper, so don't drop him in redraft just yet. But the Raiders have lost two straight after starting 3-0, and their next five opponents include the Bills, Rams, 49ers, and Seahawks — a gauntlet that could accelerate a real quarterback change if the losses pile up. Cousins is a week-to-week hold at best right now, not a lock to finish the season as the starter.

Six-of-eight for 48 yards in garbage time against a defense that had already won the game tells you almost nothing about Mendoza's readiness. The real fantasy signal here is that Kubiak wanted him on the field at all — even in a mop-up role — and Mendoza himself said having regular-season snaps to evaluate will help prepare him "if in the future I am called upon." In dynasty leagues, that future is the whole point: a brutal upcoming schedule raises the realistic floor on when Mendoza could take over. Stash him confidently if you haven't already.
