With less than two months to go before the start of the 2026 World Cup, FIFA has already clarified the rules that will define how the squads of the 48 participating teams will be formed. This tournament, to be played in the United States, Mexico and Canada, will mark a before and after in the history of soccer due to its expanded format and unprecedented logistical requirements.
For U.S. Hispanic fans, understanding these rules is key, as they will directly impact the preparation of teams like Mexico, the United States and other favorite teams.
Key dates: what you should know
The player selection process will have two determining moments:
May 11, 2026: deadline for submitting the pre-list
June 1, 2026: announcement of the final list
In the first stage, each team must submit a provisional list of between 35 and 55 players.
This group will be the official base from which the players who will play in the tournament will be selected.
An important rule is that any replacement due to injury must come from this pre-list.
This forces technicians to think strategically from the outset.
Final roster: 26 players confirmed
Another rule for the 2026 World Cup is that FIFA will maintain the format of 26 players per team, as was the case for the Qatar 2022 World Cup.
This decision responds to the need to reduce physical wear and tear, especially now that the tournament will have more matches due to the increase in the number of teams.
Of these 26 players:
At least 3 must be goalkeepers
The minimum number of players allowed is 23.
This adjustment benefits coaches, who will have more leeway for rotations, injuries and penalties during competition.

Strategy and logistics: the real challenge
One of the biggest challenges for the teams will be logistics.
With venues spread across cities such as Vancouver, Mexico City and Miami, the teams will face long journeys, time changes and different weather conditions.
In addition, clubs will be obliged to release their players on May 25, 2026.
This leaves just two weeks of preparation before the start of the tournament on June 11 at the Azteca Stadium.
This short period of time forces the coaching staff to prioritize versatile players, capable of adapting quickly to different schemes and physical demands.
Injury substitutions: clear rules
FIFA also established within its rules for the 2026 World Cup that changes to the final roster due to injury can only be made up to 24 hours before each team’s first match.
This reinforces the importance of the pre-list, as any replacement must come exclusively from that initial group.
