Absolutely gutted for Ashwin and wish him all the strength he needs in this time, it must be gut wrenching to have to deal with a personal struggle at the time of one of his biggest career achievements.
I’m not sure where to stand on subbing him out in this test. On one hand it feels like Stokes and Baz are the type of people who would hate to have gained an advantage from this and would be the first people to request that India be allowed a replacement but on the other hand it does feel like Ashwin himself wouldn’t be in favour of him being replaced in this test. I’ve seen some complaints over the precedent it could set and while I think that most of it is rubbish and could force players to play through times when they really shouldn’t be playing… it’s understandable that it isn’t an easy rule to finalise. All of that is a discussion for another day though as Ashwin and his family deserve the time and support they need at the moment.
