Asif is currently the top-ranked player of the country, while Changezi, who has of late been in a rich vein of form, is ranked fifth.
Despite being beaten 4-3 by Asif Toba in his last group match on Monday, Asif went through to the next round courtesy of his previous wins.

Toba won with a scoreline of 80-31, 01-84 (84), 63-15, 82-20, 50-85, 58-72, 72-37 (72), but it was only a consolation win for the former national champion, who failed to progress.
Meanwhile, Changezi thrashed an out-of-sorts Khurram Agha 4-1, who is currently ranked a place above him at fourth but failed to show any spark.
Defending champion and second-ranked Mohammad Sajjad will be up against Mohammad Bilal for a place in the last-four after pipping Rambail Gul 4-2 on Monday.

Bilal fended off an onslaught from third-ranked Abdul Sattar — who hit two century breaks — to ensure that he moves into the knockout stage as he won 4-3 with scores of 0-129 (125), 84-0, 59-60, 56-55, 0-116 (116), 51-48, 72-49.
In the other two last-eight encounters, Shahid Aftab will lock horns with Babar Masih and Mohammad Majid Ali will battle it out with Sharjeel Mehmood.
