I am honestly not sure how him withdrawing from IPL will protect the family. I'm sure players are under strict conditions and being monitored. The only reason I can think of is his wife (And kids) are with him in the Bio-Bubble and are uncomfortable to stay in the Bubble and he had to choose to either come out of the bubble with the family or stay and he chose to get out.
The mental pressure to sit in a bubble if he is with kids and wife when the situation outside is horrifying where people are dying left and right, you cannot blame him or anyone else who withdraw from the IPL.
Looks like KKR going win today's match. It's very important to Win today for KKR. Otherwise KKR Will drop out of the race
Only if they are able to win two matches in a row we could see any meaning in having a hope that they would even challenge for the final four.
My final four would be RCB, CSK, Mumbai and the rest of the teams will battle for the fourth spot
