The foreign players will be affected badly as the flights are suspended and some countries has banned even citizens from India and if the BCCI plans to pause the tournament they will be stuck in India until everything is sorted.
I was expecting something like this. They can't just lockup 2,000 people and then do 24x7 surveillance. At least one or two individuals will get tired of the isolation inside the bubble and go out for some adventure. The same thing happened with the PSL as well. And members from multiple franchises have now tested positive for CoVID 19 (CSK and KKR), which means that the infection is spreading inside the bubble. I don't think that the BCCI now has any option other than to postpone the tournament.
