France encountered the practical challenges of new 2026 World Cup substitution regulations during a match against Northern Ireland. Midfielder Manu Koné and defender Dayot Upamecano were among the players impacted by the rule change, with Upamecano notably forced to wait on the sideline for a full minute before he was permitted to enter the pitch.
How the New Rule Affected the French Squad
The implementation of the new substitution protocol created visible friction for the French side during their encounter with Northern Ireland. According to local media reports, Dayot Upamecano experienced the most direct delay, remaining stationed on the touchline for one minute before the officials allowed his entry into the game.

The disruption extended to other members of the squad. Manu Koné was described as a victim of the regulation’s strict application, while Michael Olise was also involved in the experimentation of these new guidelines. The incident highlights a shift in how substitutions are managed, moving away from the immediate transitions teams have historically relied upon.
Preparing for the 2026 World Cup
These adjustments are part of a broader rollout of rules intended for the 2026 World Cup. By integrating these changes into current fixtures, officials are testing the logistical flow of the game and the impact of substitution delays on match momentum.
While the French team has successfully navigated various tactical shifts in recent years, the “experimentation” phase of these rules suggests a learning curve for both coaching staffs and players. The delay faced by Upamecano serves as a concrete example of how a momentary administrative pause can affect a player’s entry into a high-stakes environment.
