A report in cricketpakistan.com.pk quoted team sources as saying that it was not unusual for the players to voluntarily leave the group -- set up by PCB for issues and recommendations related to fitness -- after they are dropped from the central contract list.
Meanwhile, left-arm pacer Wahab Riaz, who was also left out of the central contract list, is still part of the WhatsApp group.
Last week, PCB announced a list of 18 players men's central contract list for the 2020-21 season, which will come into effect from July 1. Naseem Shah and Iftikhar Ahmad were the two new faces in the list. (Also Read: Misbah-ul-Haq defends axing of senior players from PCB central contracts list)
PCB stated that Hasan, Amir and Wahab will remain in contention for selection in what will be a busier cricket season as compared to the one that has just concluded.
Following his exclusion from the list, Hasan had even posted a cryptic tweet which he later deleted. He last played for Pakistan in the 2019 World Cup clash against India at Manchester. (Also Read: PCB facing problems in sending Hasan Ali abroad for back-injury treatment owing to COVID-19 pandemic)
On the other hand, Amir last featured in the T20I series in Australia while Wahab also played his last international game in the same series.
