Cora NelsonThe Washington Nationals routed the Cleveland Guardians 10-2 at Progressive Field on May 25, 2026 — and another game is set for May 26, with Cade Cavalli (2-3, 3.86 ERA) starting for Washington. Every baseball season brings hard pitches, diving catches, and collisions at the plate. Behind each of those moments is a strict medical framework that increasingly mirrors what doctors recommend for everyday athletes: MLB's concussion protocol.
What MLB's Concussion Protocol Actually Requires
When a player shows signs of a potential concussion — a collision with the wall, a pitch to the helmet, a slide that ends badly — the protocol kicks in immediately. Under current MLB rules, the steps are:
- Immediate removal from play if any symptom is present. Athletic trainers are empowered to pull a player without waiting for the manager's decision.
- SCAT5 assessment, administered on the field or in the clubhouse, to evaluate orientation, memory, and balance.
- Mandatory 7-day injured list placement. Unlike most injuries, which allow a shorter IL stint, concussions require at minimum a week off — enforced by league rule, not just team preference.
- Independent MTBI specialist sign-off before return. Each MLB team designates an independent neurological specialist who must clear the player. The team's own medical staff cannot unilaterally approve a return.
The most important shift in protocol in recent seasons has been a move away from total rest. Research now shows that graduated reintroduction to activity — light walking, then aerobic exercise, then sport-specific drills, then full contact — leads to faster and safer recovery than lying in a dark room for days.
Why the Protocol Matters Beyond the Diamond
The reason baseball fans should care about MLB's concussion standards goes beyond what happens to their favorite shortstop. The evidence base that drives professional league protocols is the same evidence base that should guide decisions about a youth soccer player, a recreational cyclist, or a gym-goer who takes a hard fall.
According to the CDC's guidance on traumatic brain injury and concussion, the warning signs that require prompt medical evaluation include:
- Headache that worsens over 24-48 hours
- Repeated vomiting
- One pupil larger than the other
- Extreme drowsiness or inability to be awakened
- Slurred speech
- Seizures
These are emergency indicators. But milder symptoms — persistent headache, difficulty concentrating, sleep disruption, light sensitivity lasting more than a day or two — also warrant a physician visit, not just rest and a pain reliever.
When to See a Doctor After a Head Impact
The problem with concussions is that they often feel manageable in the moment. Adrenaline masks pain. Players downplay symptoms. Parents assume the child "just got their bell rung." This is precisely why the MLB protocol was designed to remove the decision from the injured person — because self-assessment after a head impact is notoriously unreliable.
For non-professional athletes, here are the clinical thresholds that should trigger a medical evaluation:
See a doctor within 24 hours if:
- Any loss of consciousness occurred, even briefly
- Memory of the event is unclear or missing (retrograde amnesia)
- A child or teenager is involved — young brains have longer recovery timelines and a higher risk of second-impact syndrome
Seek emergency care immediately if:
- Symptoms are rapidly worsening
- The person cannot recognize family members
- Vomiting is repeated (more than once)
Do not return to any sport or strenuous activity until cleared by a physician. MLB's 7-day minimum is a floor, not a ceiling. Athletes who return too soon risk second-impact syndrome — a rare but potentially fatal condition where a second concussion before the first has fully healed causes catastrophic swelling.
The Role of a Doctor in Concussion Recovery
A primary care sports medicine physician can administer standardized cognitive testing, track symptom progression, and coordinate with neurologists when needed. They can also document the injury properly — which matters if the concussion happened during work, school athletics, or an insured recreational activity.
If you are managing a child athlete's return to a competitive sport, a specialist evaluation is not optional. Schools and youth leagues increasingly require physician sign-off before return to play — partly because of liability concerns, but mainly because the science demands it. The same independent-expert standard that MLB applies to millionaire pitchers is, functionally, what every child deserves.
Platforms like ExpertZoom connect patients with sports medicine and general practice physicians who specialize in concussion management and return-to-play protocols — the same expert standard that governs the Nationals' dugout, applied to your schedule and your family.
Document the Injury from Day One
Whether the concussion happened in a recreational league game, a school sport, or a workplace accident, documentation matters. Keep a written log of symptoms, their severity, and how they change daily. Note every medical visit, every test administered, and every instruction given by a physician.
This record serves two purposes. Medically, it gives your doctor a reliable symptom timeline rather than relying on memory — which, post-concussion, is itself impaired. Legally, it creates the paper trail needed if the injury results in missed work, ongoing treatment costs, or a dispute with an insurer about the severity of the condition.
Workers' compensation claims, youth sports liability cases, and health insurance appeals all hinge on documented evidence. The same independent medical standard that MLB mandates — a specialist sign-off before return — is often required by insurers and courts before they will acknowledge the full scope of a head injury. Starting that documentation from the moment of impact puts you in the strongest possible position.
