The team management will only request replacement from the ACC technical committee if Naseem or Haris are ruled out for the next seven days
Pakistan have called up Shahnawaz Dahani and Zaman Khan as backups.
The two have been called up after Haris Rauf and Naseem Shah picked up niggles in the match against India.
This is only a precautionary measure keeping in mind the fitness and well-being of the players ahead of the ICC Men's Cricket World Cup next month.
Haris and Naseem will continue to remain under the observation of the team’s medical panel.
The team management will only request replacement from the ACC technical committee if Naseem or Haris are ruled out for the next seven days.
It is highly probable that both Haris and Naseem will miss Pakistan's last Super 4 match against Sri Lanka on Thursday, and their availability for the final, should Pakistan make it there, remains uncertain.
Following Pakistan's 228-run loss to India, Grant Bradburn, the head coach of Pakistan, discussed the status of the two pacers during the post-match press conference.
"We're taking a precautionary approach with Haris Rauf & Naseem Shah. We'll assess them tomorrow. There was no point in sending them out there to bat and potentially worsening any little niggles they've got," Bradburn said.
