Brosmer completed six of seven attempts for 58 yards in Monday night's 23-6 loss to the Bills.
Brosmer replaced Carson Wentz in the fourth quarter of Monday night's game after the offense failed to produce a touchdown drive. Week 9 was Brosmer's first appearance in a 2026 regular-season game. He will likely play a similar backup role behind newly acquired Kirk Cousins as the season progresses, at least until Kyler Murray returns from a hamstring injury.
