The Bangladesh Cricket Board (BCB) is planning to lodge an official complaint to the International Cricket Council (ICC) about South Africa’s “deplorable” sledging and poor umpiring during the Durban Test.

Bangladesh believe that South Africa’s sledging was ‘deplorable’ and the on-field umpires should have taken notice of it. Bangladesh were bowled out for just 53 on the final day as Keshav Maharaj spun a web around their batting order with a seven-wicket haul and Simon Harmer chipped in with three as well.

BCB cricket operations chief Jalal Yunus pointed out that there will be a formal complaint lodged about the first Test over the sledging issues and noted that they have already written to the ICC about the umpiring after the three-match ODI series.

“We have already lodged one complaint about the umpiring after the ODI series. The match referee had initially misbehaved with our manager, Nafees Iqbal, but then softened when we gave him a written complaint. We will lodge another official complaint about this Test match,” BCB cricket operations chief Jalal Yunus told ESPNcricinfo.

“Sledging definitely took place from both sides, but when they started it and took it overboard, we complained to the umpires. It wasn’t acceptable. We properly condemn it. We have to accept the umpires’ decisions, but the ICC must reinstate neutral umpires,” he added.

South Africa have taken a lead of 1-0 in the two-match Test series, while Bangladesh is yet to recover from the decisions that went in favour of South Africa on the fourth day’s play.

It was a surprisingly sudden end to the match after Bangladesh had hopes of possibly pulling off its first Test victory over South Africa by needing 274 runs in the final innings.

But the tourists slumped to 11/3 at the close of play on Day 4 in Durban and the wickets continued to tumble dramatically on the morning of Day 5.

No. 3 Najmul Hossain Shanto (26) and tailender Taskin Ahmed (14) were the only Bangladesh batters to reach double figures and South Africa needed less than an hour of play on Monday to take those remaining seven wickets and take a 1-0 lead in the two-Test series.
