What happened: Kyler Murray won Minnesota's starting quarterback role for 2026. McCarthy entered camp competing for the job after making 10 starts in 2025.
Why it matters: The decision turns a recent first-round pick into a developmental backup. McCarthy's long-term place in Minnesota now depends on how the Vikings manage his opportunities behind Murray.
By the numbers: Murray joined Minnesota on a one-year minimum deal, while Arizona still owes him $36.8 million for 2026.
What to watch: Watch McCarthy's preseason workload and whether Minnesota keeps him as Murray's backup entering Week 1.
