Cardiac Clearance

MLS has established a cardiac screening program that consists of a cardiac decision tree clearance within the Entrance Physical Examination performed annually and electrocardiogram (ECG) and echocardiogram screening biennially.

Under the direction of MLS consulting cardiologist, Dr. Matthew Martinez, MLS Clubs implement the MLS cardiac screening program that includes cardiac screenings and ECG and echocardiograms for all Players.

All participation and return to play decisions are made by the Club Physicians and Club Cardiologists in accordance with the current American Heart Association (AHA)/American College of Cardiology (ACC) Guidelines for sports participation. The club team doctor has the final say in consultation with the club Cardiologist. Any deviations from accepted guidelines require consultation with the league medical department.

Club Cardiologist:

Each MLS Club is required to maintain a Club Cardiologist throughout the season. The Club Cardiologist specializes in the diagnosis, treatment, and management of cardiovascular diseases with experience in sports cardiology.

The Club Cardiologist is present for and assists in pre-season physicals, provides further evaluation, treatment, and recommendations for players with abnormal history/physical exam findings/or abnormal screening ECGs, provides the interpretation of ECGs and echocardiograms, and assists in participation and return to play determinations.

Required Cardiac Screening:

All Players must participate in cardiac screening before being cleared to participate, including practice or competition, with the Club. In addition to annual pre-participation screening, all Players will undergo biennial (every two years) ECG and echocardiogram screening, with additional follow-up as indicated. Cardiac Screenings include the following:

  • Annually:
    • Focused American Heart Association (AHA) 14-element cardiac history and physical examination
  • Biannually (every two years):
    • Resting 12-lead electrocardiogram (ECG)
    • Resting Echocardiogram

Emergency Preparedness

MLS, the MLS Players Association, and Club Medical Staff work collaboratively year-round to prepare for potential medical emergencies because a rapid medical response from trained individuals improves the odds of a favorable outcome.

Each Club is required to submit their On-Field Emergency Action Plan for Club venues, including practice, competition and strength training/performance, to the League before the start of pre-season training.

On-Field Emergency Response Plans are required to detail:

  • Chain of command
  • Roles and responsibilities
  • Equipment information and location (e.g., AED, spine boards, splints)
  • Communication
  • Transportation
  • Emergency facilities (e.g., closest hospital for cardiac, neurological or trauma)

These plans are reviewed and practiced formally prior to the season by Club Medical Staff and shared with all stakeholders. Players, coaches, officials and other staff members understand their roles as either first responders if trained or bystanders in case of an emergency, including the location of potentially life-saving equipment (e.g., AED).

Before every MLS match, the Venue Medical Director oversees a mandatory pre-match “medical time-out” meeting with medical staff from both teams, the Fourth Official, EMT staff, and additional personnel from the Club Operations and Security staff.

The “medical time-out” reviews the venue On-Field Emergency Action Plan, including introduction of staff, roles and responsibilities for different emergencies, and the outlining of methods of communication and the locations of emergency equipment and ambulances.

Required Gameday Care Team

Every game day, MLS policy requires the following to be present:

  • At least two certified athletic trainers/therapists on each bench
  • A physician on the home team bench
  • A Venue Medical Director (VMD)
  • Two ambulances (with Advanced Life Support and Emergency Medical Technicians)

In addition, visiting teams are encouraged to travel their own team physician positioned on the visiting team bench.

MLS Medical Spotter Program 

Head injuries in soccer often occur at high speeds and sometimes with obstructed line of sight for Club Medical Staff. MLS has implemented programs during games to provide the Venue Medical Director and Club Medical Staff with technological assistance in early detection of the injury.

The League Spotter is a designated observer who is a medical professional trained by the League and tasked with providing an “extra set of eyes” for the Venue Medical Director / Club Medical Staff.

The League Spotter reviews live video feeds of the match (with rewind capabilities) to observe for any Mandatory or Discretionary Observable Signs of possible concussion as outlined in the MLS Head Injury / Concussion Evaluation and Management Protocol (MLS Concussion Protocol). The role of the League Spotter is to aid in the recognition of a possible head injury, not to diagnose a concussion. League Spotters are not authorized to stop the game or remove a Player from play for evaluation, instead, the Venue Medical Director and Club Medical Staff are in charge of injury assessment.

When a head injury or suspected head injury occurs , video of the injury is “clipped” by the League Spotter and sent to the Venue Medical Director who can view the feed on a monitor that is kept at the Fourth Official’s table during the match. Ideally, several views are included and the mechanism of injury as well as Observable Signs are recorded.

If a mechanism of injury is observed, and any of the Mandatory Observable Signs are identified by the League Spotter, they will communicate immediately to the Venue Medical Director that an on-field assessment is required per the MLS Concussion Protocol. When there is an on-field assessment, the Venue Medical Director must review the available video prior to allowing the Player to return to play.

If a Discretionary Observable Sign is observed, the League Spotter relays the information to the Venue Medical Director along with a video clip of the incident.

The Venue Medical Director may share this content with Club Medical Staff.
