The 21-year-old left-arm paceman had a MRI scan after he felt pain during his three-over spell in the match, which revealed a partial tear.

“The scan revealed a partial tear of the abdominal muscle which requires six weeks of rest,” said assistant team manager Naushad Ali. “He is out of the Bangladesh tour and needs rehabilitation.” Khan’s injury is the second blow to Pakistan after allrounder Abdul Razzaq was Tuesday ruled out of the tour with a shoulder injury.

Pakistan have already announced a 16-man squad for the tour of Bangladesh where they play one Twenty20 match, three one-day internationals and two Tests, starting with the Twenty20 in Dhaka on Tuesday.

Ali said Pakistan Cricket Board’s selection committee would in time name replacements for the injured duo.

Khan, who made his Test debut on the tour of Zimbabwe in September this year, has so far played four Tests, nine one-day internationals and two Twenty20s.
