Each country playing at Euro 2020 this summer will be allowed a squad of 26 and will be able to replace players who test positive for Covid-19 up until their first match.
UEFA has confirmed the increase in squad numbers from the usual 23 players to 26 in light of the tournament being played in extraordinary circumstances amid the pandemic.
The expanded squads will ease the situation if one or more players within the camp test positive for coronavirus and have to self-isolate during the finals, which begin on June 11.

UEFA confirmed, however, that only 23 players can be selected for each individual match, with the other three not included on the teamsheet.
That is because the laws of the game state that a maximum of 12 substitutes are permitted for top level international matches.
But in a further easing of the rules, UEFA will permit national team managers to make unlimited replacements of players within the 26-man squad right up until their first fixture.
That means if a player is injured or falls ill after the squads are submitted on June 1, there is a window within which they can be replaced by someone else.

The new rules also allow goalkeepers in the squad to be replaced throughout the tournament if they test positive for Covid-19.
But once a player has been taken out of a squad, they cannot then be readmitted.
Teams will be able to make five substitutions during matches at the tournament.

The Covid-19 pandemic has forced the relocation of some matches from their original venues because UEFA wanted stadiums to be at least a quarter full of spectators.
That led to Dublin being removed as one of the 12 host cities, with matches scheduled for there going to Saint Petersburg and Wembley.
