Bangladesh Cricket Board president Ali Asghar said he had contacted his Pakistani counterpart Shaharyar Khan to express his backing on the issue.
''I told him (Shaharyar) that we are with Pakistan as they had supported us on many occasions,'' Asghar told the reporters.
''I have gone through the whole incident and found nothing wrong in Pakistan's reaction.'' On Sunday, umpires Darrell Hair of Australia and Billy Doctrove from West Indies decided that Pakistan had forfeited the match when they failed to take the field after the tea interval.
Pakistan were incensed that the umpires had decided they had been guilty of ball tampering, docking the team five runs, and staged a protest by staying in the dressing room for several minutes.
Pakistan captain Inzamam-ul-Haq was charged with ball tampering and bringing the game into disrepute and could be banned for eight One-day Internationals or four Tests if found guilty.
The Sri Lankan cricket board have already given their backing to Pakistan
