The PCB have also confirmed the departure of Grant Bradburn and Andrew Puttick just nine months after the men's brains trust was formed amid much fanfare last year
Mickey Arthur's ill-fated return to Pakistan is over after just nine months, bringing an end to his duel role as head of cricket with Derbyshire.
The 55-year-old, a former head coach between 2016 and 2019, returned as team director last April.
But after not being involved in Pakistan's tours of Australia or New Zealand and being reassigned to the National Cricket Academy in Lahore following the group stage exit from the Men's Cricket World Cup in India, he has stood down.
"Thank you Pakistan....it has been a pleasure!" Arthur, a former South Africa, Australia and Sri Lanka head coach, wrote on Twitter to make the end of his nine-month stint.
The PCB have also confirmed that Grand Bradburn, head coach for the tournament, and batting lead Andrew Puttick will leave their contracts at the end of the month.
Bradburn, a former assistant and head of high performance, was installed as Glamorgan head coach on January 8 and begins his new role in South Wales in the coming weeks.

A PCB statement said the decisions had been "taken amicably between all the stakeholders" and wished "them well in their future endeavours and is grateful for their services".
Mohammad Hafeez was installed as Pakistan team director and head coach for the Test series against Australia (lost 3-0) and the ongoing five-match T20I series in New Zealand (the Kiwis hold an unassailable 3-0 lead with two to play).
Arthur is in the midst of a lengthy contract at Derbyshire which still has two seasons to run.
Though the terms of the relationship between Derbyshire and the PCB included the stipulation that Arthur attended all of the county's matches during the English summer, his full focus will now be on the Division Two side.
The first year of the partnership saw Derbyshire's results noticeably nose-dived, failing to win a County Championship match or reach the knockout stage of either domestic white-ball competitions.
