Shadab Khan is the latest Pakistan player to be ruled out of the Boxing Day Test against New Zealand.
All-rounder Shadab captained the tourists in a 2-1 Twenty20 International series defeat to the Black Caps after Babar Azam missed out with a fractured right thumb.
Shadab will play no part in the first Test at Mount Maunganui, which starts on Saturday, after sustaining a thigh injury.
The extent of the damage done by Shadab will be revealed after he has undergone MRI scans in Tauranga on Thursday.
Pakistan have drafted in uncapped left-arm spinner Zafar Gohar in the absence of Shadab.
Opening batsman Imam-ul-Haq also misses the opening match of the series with a thumb injury.
