I do not think it is possible to postpone IPL. I think they might not allow spectators to come to the stadium.
If it is to be true, I think it's better to postpone the IPL, why not. Otherwise, this season, IPL will face a huge loss. There is nothing wrong in postponing the season, may be it will be hard to get a schedule later but still it is better than facing a loss.
@pakhittheboss my Indian friends have informed me that the virus is spreading really fast out there, and BCCI has two options out in their hands i.e. one allow spectators inside and sanitise them or play the match behind closed doors and let people watch it live from their homes. @Little Mouse don’t worry the IPL won’t be postponed under any scenario because BCCI loves money, and they’ll do everything in their power to keep the league alive but we will have to wait for few more days to see what solution do they come up with.
