England wicketkeeper Jonny Bairstow says his alleged headbutt on Australia batsman Cameron Bancroft has been “completely blown out of proportion”.

The incident, which took place on a night out in Perth in October, came to light during the hosts’ 10-wicket win in the first Test in Brisbane.

Bairstow and Bancroft said there was “no malice” in the action.

England coach Trevor Bayliss said his players have “got to be smarter” away from the pitch.

Bairstow will not be disciplined over the incident, but England’s players have effectively been grounded, said BBC cricket correspondent Jonathan Agnew.
