In total, more than 150 players in both the men’s and women’s competitions have been retained.
There was no limit on the number of players the women’s teams could retain from last year, while men’s teams were permitted to keep up to 10 players as well as at least one England Test contracted player.
Men’s players who have not been retained will go into The Hundred draft on 30 March.
The draft will be conducted in reverse order of the 2021 finishing positions, with London Spirit getting the first pick.
Women’s players who have not been retained are now free to be signed by other franchises and those signings, both domestic and overseas, will also be announced on 30 March.
Both men’s and women’s sides will be able to sign a fourth overseas player in a wildcard draft in June, but can only field three overseas players in a starting XI when the tournament begins.
In the men’s competition, Quinton de Kock, David Warner, Kane Williamson, Nicholas Pooran, Kagiso Rabada, Kieron Pollard, Adam Zampa, Mohammad Amir and Aaron Finch are among the international stars not retained.
In the women’s competition, Meg Lanning, Beth Mooney and Nicola Carey – who all had to withdraw last year – have been released.
The men’s and women’s overseas stars may still feature in this summer’s Hundred as teams should have a better idea by the time of the draft which international players will be available and for how long.
The 2022 Hundred starts with a men’s fixture between champions Southern Brave and Welsh Fire at the Ageas Bowl on Wednesday, 3 August.
The women’s competition begins on Thursday, 11 August, following the Commonwealth Games in Birmingham, with champions Oval Invincibles hosting the Superchargers at the Kia Oval in a double header following the men’s game.
The final of the 100-ball tournament, which launched last year, will take place at Lord’s on 3 September.
