No handshakes post-match
This was a thing adopted during the one ODI played between Australia and New Zealand at the Sydney Cricket Ground, which was played behind closed doors. Instead of high fives and shaking hands when a wicket fell, playing were touching elbows to celebrate. Also Australia captain Aaron Finch and New Zealand captain Kane Williamson touched elbows during the toss.

Touching elbows were also seen when the match ended and players from both sides met. This may become a norm in the coming times, when cricket returns in post-COVID 19 world, as players might want to keep themselves safe from touching one another, given that it is a way to spread Coronavirus.
Also, the teams clapped for each other after the game got over, instead of following the tradition of shaking hands.
