Liga Portugal’s Purple Card: Innovation in Concussion Protocol and Health at EXPOFUT

Liga Portugal is establishing a pioneering approach to player safety by introducing the purple card system for concussion substitutions, a development highlighted by health coordinator André Moreira ahead of the inaugural EXPOFUT event scheduled for February 14 and 15 at the Arena Liga Portugal in Porto, as reported by Record.

The Operational Mechanics of the Purple Card

The introduction of the purple card serves as a visible regulatory response to head trauma during matches in the Liga Portugal Betclic and Liga Portugal MeuSuper competitions. While FIFA’s FOCUS project establishes the on-field evaluation protocol for suspected concussions, Liga Portugal implemented the purple card to signal an immediate, extra substitution that does not count toward a team’s standard limit.

When a club medical team suspects a concussion, the player leaves the pitch and the purple card is raised by the team’s technical delegate. According to league officials, the referee does not issue the card because the decision is purely clinical rather than a disciplinary sanction under the Laws of the Game. The visible indicator ensures that spectators, opponents, and television viewers immediately recognize that a player has departed for health reasons rather than tactical adjustments.

Clinical Autonomy and Resistance on the Pitch

League data shows that the protocol has operated without resistance from clubs or opposing benches during its initial implementations. Moreira noted that clinical staff hold total autonomy in making the decision, though players occasionally resist leaving the match due to competitiveness. In one instance, a player evaluated under the protocol returned to the pitch only to be re-evaluated and removed at halftime, demonstrating that head injury assessment extends beyond the initial minutes of an incident.

FIFA Reviews Portuguese Concussion Substitution Framework

The visible implementation of the concussion substitution rule has drawn inquiries from other international leagues and sports federations seeking to understand the Portuguese framework. Representatives from FIFA visited Portugal to review the initiative, expressing positive feedback regarding how local data aligns with global safety recommendations.

Pillars of Future Player Welfare

Looking beyond concussions, Liga Portugal has structured its health strategy around three core pillars: knowledge based on empirical data, regulatory protection for athletes on the field, and emergency medical preparation across all league stadiums. The league previously established a concussion working group and published the first formal study on the topic within professional Portuguese football.

Future health initiatives identified by the league include managing fixture congestion and recovery times, expanding rigorous data tracking for injury prevention, standardizing emergency responses at all venues, and broadening player wellness to encompass mental health, sleep, nutrition, and oral care.

The EXPOFUT event opens at the Arena Liga Portugal in Porto on February 14 and 15, with further industry panels and technology exhibitions scheduled through February 15.
