Pakistan on Monday named limited-over opener Fakhar Zaman, uncapped quick Mir Hamza and all-rounder Shadab Khan in the 12-man squad for the second Test against Australia at Sheikh Zayed Stadium, Abu Dhabi.
Left-arm quick Wahab Riaz has been dropped for the series decider, Pakistan captain Sarfraz Ahmed confirmed on Monday.
Wahab, who returned to the side after a year, failed to impress in the first Test where he returned wicketless after bowling 27 overs.
Fellow left-armer Hamza appears the most likely man to replace him, though Shadab, who has recovered from a groin injury, could be considered if Pakistan want another spin-bowling option.
In the batting department, Fakhar is in line to make his Test debut, and replace injured Imam-ul-Haq, who fractured his finger in the drawn opening Test.
