According to unconfirmed media reports, the Bangladesh Cricket Board (BCB) is threatening to pull out of the ICC Men's T20 World Cup, unless their matches are shifted to Sri Lanka. The ICC hasn't yet reacted positively, and are considering other options as well. One option in front of ICC is to replace Bangladesh with the next highest ranking team in the T20I rankings table (which happens to be Scotland, who are ranked 14th). This is like a nuclear option for the ICC and I am not sure whether they will go that far. At this point, we can't rule out any of the possibilities.
I think at the end of the day this is going to be happening because at some point there was a rumor that Ireland team was agreed to group changing to Bangladesh and then there will be no tention But it is being heard that the BCCI and the Ireland Cricket Board have reached an agreement and for this, the Ireland team is currently not willing to shift groups. As a result, the ICC will have to select Scotland as Bangladesh's replacement.
But what is more interesting here is that now the Pakistan Cricket Board has spoken in support of the Bangladesh Cricket Board that they will reconsider participating in this year's ICC World Cup if the Bangladesh team is out of this tournament. Then the ICC will probably lose a huge amount of revenue in this tournament. And at the same time, it is going to be one of the worst hosted cricket tournaments in history.
