Pakistan are 87-1 in their first innings in reply to Bangladesh's 338, with Taufeeq Umar unbeaten on 44 and Azhar Ali 26 not out.
Pakistan lost in-form Mohammad Hafeez before Umar and Azhar put on 64 runs for the unbroken second-wicket stand, with Umar hitting eight fours in his 79-ball knock so far.
Bangladesh paceman Nazmul Hossain, returning to the Test side after seven years, struck with his first delivery when he had Hafeez caught behind for only 14, a stark contrast to the opener’s 143 in the last Test.
