Pakistan will be without Haris Rauf for their second Test against England in Multan, with the quick bowler potentially set to miss the rest of the series with a quad injury.
The 29-year-old stepped on the ball while fielding during the hosts' 74-run defeat in Rawalpindi and did not bowl in the second innings.
Now, having undergone MRI scans, Rauf – who made his Test debut in the match – has been a confirmed absentee for his side's next match, in what is a significant blow.
Despite an underwhelming performance against England, his departure - and potential unavailability - for the rest of three-game tour could throw a spanner in their selections.
With Shaheen Afridi already unavailable, Pakistan may have to call upon a name from outside their original 18-man squad, with Mohammed Wasim Jr their only other specialist quick currently in their party.
Hasan Ali and Mohammed Abbas are both among those who could be drafted in, though whether Babar Azam would wish to call upon them at short notice remains to be seen.
Faheem Ashraf and Mohammad Nawaz both offer all-rounder experience and are in the squad already, though their inclusion would require a reshuffle in the batting order.
Pakistan will start their second Test on Friday, as they look to bounce back from just a third red-ball defeat on home soil against England, and first since 2000, upon the tourists' return to the country.
An aggressive encounter with the bat saw the two sides rack up the third-highest aggregate score in a match in Test history, in a record-shattering encounter.
