Shoaib Malik is expected to travel to Southampton on August 15 provided he returns two negative coronavirus tests, giving him enough time to integrate with the squad before the T20I series.
Malik was initially named among the 29 members selected for the England tour but he had to experience a delay in joining the national side in order to spend time with his family in India.
The veteran all-rounder has been unable to meet them since the start of the year due to border restrictions enforced amidst the Covid-19 crisis.
Malik was originally scheduled to fly out to England towards the end of July but India opened its borders for international travel only recently causing the PCB to change their plans.
The 38-year-old senior pro will be part of the team for the three T20Is that will all take place behind closed doors at Old Trafford starting August 28.
Malik has restricted his appearances solely for the T20 format since retiring from 50-over cricket last year at the World Cup.
Although he was dropped for the Australia tour later in November, Malik returned to the side for the three-match T20I series at home against Bangladesh.
He has declared his intention to quit international cricket after representing Pakistan at the T20 World Cup one last time.
Meanwhile, Pakistan assistant coach Shahid Aslam will rejoin the cricket contingent in Manchester on August 8 after arriving in Lahore last week to attend his father's funeral.
