Vikings QB J.J. McCarthy Enters Concussion Protocol, Max Brosmer Expected to Start in Week 13

Vikings Confirm J.J. McCarthy Placed in Concussion Protocol

Minnesota Vikings Head Coach Kevin O’Connell confirmed on Monday that rookie quarterback J.J. McCarthy has been placed into the NFL’s mandated concussion protocol. The move comes after McCarthy reported symptoms to the team following the previous week’s contest, immediately raising questions about the Vikings’ starting lineup for their crucial Week 13 matchup.

McCarthy, who has been a central figure in the Vikings’ offense this season, will now begin the rigorous process required to be cleared for play. His immediate status makes him highly unlikely to participate in the upcoming game, forcing the team to adjust its quarterback depth chart.

The Immediate Impact: Max Brosmer Steps Up

With J.J. McCarthy sidelined indefinitely due to the protocol, Coach O’Connell indicated that the team is preparing to start quarterback Max Brosmer for the Week 13 game. This transition marks a significant shift for the Vikings as they navigate a critical stretch of the 2025 season.

Brosmer, who has been serving as the primary backup, will be tasked with leading the offense against a yet-to-be-named opponent. The preparation timeline is tight, and the focus will immediately shift to ensuring Brosmer is fully prepared to execute the game plan.

Vikings Quarterback Situation

Understanding the NFL Concussion Protocol

McCarthy’s placement in the protocol is mandatory once a player reports symptoms or is diagnosed with a concussion. The NFL’s protocol is a strict, five-step process designed to ensure player safety and prevent premature return to play, which could lead to severe long-term health consequences.

It is crucial for fans and analysts to understand that there is no fixed timeline for a player to clear the protocol. Each step requires the player to be symptom-free and tolerate increasing levels of physical exertion without symptoms returning.

The Five Steps of Clearance

1. Symptom Limited Activity: Rest and recovery, limited to stretching and balance activities. The player must be symptom-free at rest.
2. Light Aerobic Exercise: Introduction of light cardio, such as stationary cycling or walking.
3. Football Specific Exercise: Introduction of more intense aerobic activity and supervised strength training.
4. Club-Based Non-Contact Training Drills: Participation in non-contact practice drills, allowing for increased cognitive and physical exertion.
5. Full Football Activity/Clearance: Full participation in practice after clearance by both the team physician and an Independent Neurological Consultant (UNC). The UNC’s clearance is the final, non-negotiable step.

“The priority is always the health and safety of our players. J.J. reported the symptoms, and we immediately followed the protocol. We will not rush this process,” Coach O’Connell stated, emphasizing the team’s commitment to player welfare.

Implications for the Vikings’ Playoff Push

McCarthy’s absence, even for a single game, is significant, especially given the competitive landscape of the 2025 season. As the Vikings fight for a playoff spot, losing their starting quarterback—particularly one who is still developing—puts immense pressure on the coaching staff and the rest of the roster.

Max Brosmer will need to rely heavily on the Vikings’ established running game and strong defensive unit to manage the game effectively. The offensive scheme may need to be simplified initially to minimize risk and capitalize on Brosmer’s strengths, which typically include quick decision-making and efficient short-to-intermediate passing.

This situation highlights the critical importance of quarterback depth in the modern NFL. While McCarthy’s development is paramount, the team must now rely on Brosmer’s preparation and ability to perform under unexpected circumstances.

Key Takeaways for Vikings Fans

• J.J. McCarthy is officially in the NFL’s concussion protocol, announced by Coach Kevin O’Connell on Monday.
• McCarthy reported symptoms following the team’s Week 12 game.
• He is highly unlikely to play in Week 13 due to the mandatory clearance process.
• Max Brosmer is being prepared to start at quarterback for the Vikings.
• The team must prioritize player safety, meaning McCarthy’s return timeline is dictated entirely by his recovery and medical clearance, not the schedule.

What’s Next

The Vikings will monitor McCarthy’s progress through the protocol daily. Updates regarding his status will be limited until he reaches the final stages of clearance. All eyes will now be on Max Brosmer as he takes over the starting duties, with practices throughout the week determining the final offensive strategy for the pivotal Week 13 contest. The team’s ability to rally around Brosmer will be crucial in maintaining their competitive standing in the NFC.
