ESPNcricinfo understands that Verma, 17, has already signed a contract with two-time champions Sydney Sixers while Yadav, 21, is on the verge of finalising her deal with one of the two Sydney-based clubs. Aside from Verma and Yadav, at least one more India player is likely to make her maiden appearance in the competition this season.
"Yes, Shafali has signed the contract with Sydney Sixers, and given she is a minor, I have had to give my consent, too," Verma's father, Sanjeev, told ESPNcricinfo. "I would like to thank the BCCI and Haryana Cricket Association [HCA] for giving my daughter the permission and support to play in the WBBL. Without the guidance of the HCA, whatever Shafali is doing in her career wouldn't have been possible."
A senior BCCI official told ESPNcricinfo that the WBBL could see the largest ever Indian contingent this season. "All players who have been or will be approached by Big Bash teams will be given all necessary permissions to participate in the WBBL this season," he said on the condition of anonymity.
Verma, as reported by ESPNcricinfo last week, is also set to make her debut in the inaugural edition of the Hundred, the 100-ball domestic competition of the ECB. She will be joined by her India team-mates Harmanpreet Kaur, Smriti Mandhana, Deepti Sharma and Jemimah Rodrigues.
Only three India players have played in the WBBL previously. India T20I captain Kaur and vice-captain Mandhana debuted in the 2016-17 edition for the Sydney Thunder and the Brisbane Heat respectively. While Kaur played three straight seasons for the Thunder, Mandhana's second bow in the competition was for the Hobart Hurricanes, in 2018-19. Veda Krishnamurthy played a solitary season, in 2017-18, also for the Hurricanes.
The WBBL didn't have any Indian representation in 2019-20 as they focussed on preparing for the 2020 T20 World Cup instead, with assignments against South Africa and West Indies during the same time as the WBBL. A clash in scheduling with the 2020 Women's T20 Challenge, the domestic three-team, four-match competition run by the BCCI, ruled at least three top-drawer India players out of the WBBL.
The seventh season of the WBBL is likely to run in its usual October-November window, and overseas players will be expected to undergo a mandatory 14-day quarantine on arrival in Australia.
