England coach Gareth Southgate will name a provisional extended squad ahead of Euro 2020, the FA said on Monday.
A tweet from the official England account said Southgate would announce the squad before speaking to the media at 1400 local time (1300 GMT) on Tuesday.
The group will then be reduced to 26 players ahead of the June 1 deadline for squads to be submitted to UEFA ahead of the June 11-July 11 tournament being held across Europe.
While the FA did not confirm the size of the squad Southgate is likely to name, various local media reports suggested it could contain more than 30 players.
It is believed Southgate's decision is to allow for key players such as Harry Maguire and Jordan Henderson every chance to prove their fitness as they recover from injury.
It also factors in the number of England players involved in Wednesday's Europa League final between Manchester United and Villarreal, as well as Saturday's Champions League final between Chelsea and Manchester City.
Other nations, including the Netherlands and Italy, have named extended squads that will then be whittled down, while others, such as Spain, have not used their full allocation of 26 players available to them.
