All the current male players are invited to participate in the pilot matches, which will take place from September 16-18, while the women’s trials are scheduled for September 14, 15 and 27.

“We are hopeful the majority of counties will have a representative, although with some counties having first XI and second XI fixtures it will not be possible to have a player from each of the 18 counties.

“All current male players have been contacted to notify them of the details for the pilot matches, with player availability co-ordinated via the counties and the ECB.”

The ECB has planned to start the tournament from 2020.

The 38-day tournament will involve eight teams, including a play-off system and players’ draft. Lord’s, The Oval, Ageas Bowl, Edgbaston, Headingley, Old Trafford and Sophia Gardens are the other venues that are likely to host the matches.
