Kaur was found to have breached Article 2.1.3 of the ICC Code of Conduct for Players and Player Support Personnel, which relates to “Showing dissent at an umpire’s decision during an International Match.”
The charge was brought by on-field umpires Billy Taylor and David Millns.
The batter admitted the offence and accepted the sanction proposed by ICC Match Referee David Jukes. As such, there was no need for a formal hearing.
