Vikings to start rookie QB Max Brosmer vs. Seahawks with J.J. McCarthy in concussion protocol

Minnesota Vikings head coach Kevin O'Connell announced that undrafted rookie Max Brosmer will start Sunday's game against the Seattle Seahawks. This decision comes as J.J. McCarthy remains in the league's concussion protocol following symptoms reported after the team's Week 12 loss to the Green Bay Packers. McCarthy has been limited in practice this week.

Sunday will mark Brosmer's first career start. His only prior NFL game action occurred when he completed 3-of-4 passes in relief of then-starter Carson Wentz during a loss to the Los Angeles Chargers on October 23. Brosmer, who set a school record with 268 completions at the University of Minnesota, was a notable undrafted free agent prospect after the 2025 NFL Draft. He moved up to the No. 2 quarterback position following Wentz's season-ending shoulder surgery in late October.

This will be McCarthy's sixth missed game of the season, having previously missed five games due to an ankle injury.
