On a dry Rawalpindi field that is predicted to take spin, England selected Rehan Ahmed as a third slow bowler on Tuesday for the series-deciding final Test match against Pakistan.
When the game starts on Thursday, the 20-year-old leg-spinner will join left-armer Jack Leach and off-break bowler Shoaib Bashir to form a three-pronged spin attack.
England won the first Test by an innings and 47 runs in Multan, tying the three-match series at one.
Pakistan won the second game by 152 runs on the same ground, and their spinners claimed all 20 wickets.
Fast bowlers Matthew Potts and Brydon Carse were dropped from the team, and seam bowler Gus Atkinson was called up.
