Minnesota Vikings' rookie quarterback J.J. McCarthy will miss the entire 2024 NFL season due to a full meniscus repair on his right knee, which he underwent on Wednesday. The injury occurred during a preseason game against the Las Vegas Raiders, and initial optimism that a minor trim might suffice was dashed upon further medical evaluation. The Vikings had hoped McCarthy could serve as a developmental backup to veteran QB Sam Darnold, who now solidifies his position as the starter for the upcoming season. Despite the setback, the team remains optimistic about McCarthy's long-term career prospects. This injury interrupts the Vikings' transition plan from former quarterback Kirk Cousins and puts a damper on their 2024 season outlook.
