The PCB was in talks with the Emirates Cricket Board to seek permission from the UAE government to hold the remaining 20 matches of the PSL in Dubai and Abu Dhabi from 1 June.
PSL was postponed on 4 March in Karachi after an outbreak of positive cases among the franchises.
PSL 2021: PCB says UAE 'preferred venue' to complete tournament amid spike in COVID-19 cases in Pakistan
A recent spike in COVID-19 cases in Pakistan had forced the six PSL teams to write to the PCB last week to shift the rescheduled games from Karachi to the UAE.
The PCB had to postpone PSL-6 abruptly on 4 March with just 10 out of 34 matches completed due to COVID-19 cases among players and officials.
The franchises have asked the Pakistan Cricket Board (PCB) to call a meeting of the PSL governing council after it became apparent that many of the overseas players, who appeared in the league in February-March, might not be available on resumption.
The six-team Pakistan Super League (PSL) will start again on 1 June, the controlling board announced on Sunday, with all 20 remaining matches to be played in the port city of Karachi.
"It appears they didn't have a plan B when the COVID-19 cases were detected among some players and officials and this is surprising to me. The postponement didn't send out a good message," Afridi said.
The PCB decided to adopt a safety-first approach soon after the official tested positive and asked its employees to work from home.
Islamabad United’s two foreign cricketers, including Australian leg-spinner Fawad Ahmed, an unnamed foreign cricketer and a support staff member from one of the teams were already in isolation after being tested positive earlier this week.
The PCB said in a statement that the three players are from two different teams and they will now self-isolate themselves for 10 days.

Quetta’s victory after four straight losses ended a 13-match streak of teams successfully chasing down the targets since the tournament began on 20 February.
Steyn said he took the break as he needed time off from the game and also because he found playing in other leagues around the world more rewarding as a player.
Many reports in the Pakistan media blamed PCB for the positive test incident which has cast a shadow on the league.
The Pakistan Cricket Board (PCB) said all remaining members of Islamabad United have tested negative.
Afridi returned figures of 3-27, with his bowling reaching speeds of 94 mph (around 150 kph). That helped to restrict Karachi to 186-9 despite half-centuries by Sharjeel Khan (64) and Afghanistan’s Mohammad Nabi (57).
