The Bangladesh U-19 team was scheduled to tour Pakistan from later this month but a Pakistan Cricket Board (PCB) official said that they have got a request from their counterpart to postpone the series.
The official declined to give reasons for the BCB's decision but said the series could be played at a later date this year.
Sources in the board said the BCB's request could stem from security concerns about playing in Pakistan in present situation, although the Pakistan Football Federation hosted the Bangladesh team for a World Cup qualifying match in Lahore on Sunday.
The Bangladesh football officials had also initially asked the sport's world governing body to move their World Cup qualifying match against Pakistan from Lahore but their request was rejected despite their security concerns.
Bangladesh football team coach was fired for refusing to go to Pakistan.
