After their attempt to play an all-pace assault on a slow track in the series opener in Rawalpindi last week backfired, Pakistan called up leg-spinner Abrar Ahmed on Wednesday for the second and final test against Bangladesh.
Pakistan, who fielded an attack without a single frontline spinner, lost to Bangladesh on Sunday in their first-ever test match.
Their pacers struggled miserably on a slow pitch, but spinners Shakib Al Hasan and Mehidy Hasan Miraz combined for seven wickets to bowl Bangladesh to an unforgettable victory of ten wickets.
The roster has been augmented by Abrar, an uncapped spin bowling all-rounder with 38 wickets from six tests, and Kamran Ghulam.
The PCB added in a statement that all-round player Aamer Jamal had also been summoned back, although his participation was contingent on receiving a fitness clearance.
On Friday, the last exam will start in Rawalpindi as well.
