Chris Broad of the Emirates Elite Panel of ICC Match Referees imposed the fine after Mashrafe Bin Mortaza's team was ruled to be one over short of its target when time allowances were taken into consideration during the match on Wednesday.
In accordance with Article 2.5.1 of the ICC Code of Conduct for Players and Players Support Personnel, which relates to minor over-rate offences, players are fined 10 per cent of their match fees for every over their side fails to bowl in the allotted time, with the captain fined double that amount.
For a captain to be suspended during an ICC event, he must commit two minor over-rate offences or one serious over rate offence during the event. Therefore, if Mashrafe is found guilty of one more minor over-rate offence during the ICC World Twenty20 while acting as captain, he will receive a one-match suspension during the event.
Mashrafe pleaded guilty to the offence and accepted the proposed sanction, so there was no need for a formal hearing, the ICC said.
