The 2026 World Cup is a month away, and the squad selection game is already producing winners and losers. Argentina's preliminary list landed this week — and Paulo Dybala wasn't on it. Forty caps, two World Cups, and he's watching from home. That's how these things go.
But what exactly is a preliminary squad, and how does the whole process work before nations lock in their final 26?
The Preliminary List: A Longlist With Real Consequences
FIFA allows participating nations to submit a provisional release list of between 35 and 55 players, with at least four goalkeepers included. These lists aren't published by FIFA — nations choose whether to go public — but the governing body uses them to collect key player data well in advance of the tournament.
Here's the part that matters: if you're not on the preliminary list, you're not going to the World Cup. Full stop. Dybala's omission from Argentina's provisional squad isn't just a statement of form — it's a closed door. He hasn't played for the Albiceleste since September 2024, so it's hard to call it a surprise, but the finality is real.
The final squads must be confirmed by FIFA on June 2 — nine days before the tournament opener, Mexico vs. South Africa. Bosnia and Herzegovina were first to announce, going public on May 11, though lists aren't official until FIFA validates them.
Final Squad Size and Injury Rules
The maximum squad size stays at 26 — the expanded format that debuted at Qatar 2022 — with a minimum of 23 and at least three goalkeepers required.
Between the preliminary list submission and the final deadline, coaches can make changes — but only for injuries or illness, and only if FIFA's Medical Committee signs off. Any replacement must come from the original provisional list. Once a player's team kicks off their first match, that's it — no more swaps, except for goalkeepers.
The goalkeeper exception has precedent. At Euro 2020, Aaron Ramsdale replaced Dean Henderson in England's squad after Henderson was ruled out with a hip injury. Same rules apply here under FIFA.
- Preliminary squad size: 35–55 players (min. 4 goalkeepers)
- Final squad size: 23–26 players (min. 3 goalkeepers)
- Final lists confirmed by FIFA: June 2
- Tournament opener: June 11 — Mexico vs. South Africa
- Injury replacements allowed until 24 hours before a team's first match
- In-tournament replacements: goalkeepers only
For anyone tracking squad depth and rotation odds going into the tournament, the preliminary lists are worth watching closely. A 55-man pool tells you a lot about where a manager is uncertain — and uncertainty in key positions tends to show up on the pitch in the opening group games.
