Australia opener David Warner has been fined 15 per cent of his match fee after pleading guilty to a charge of making inappropriate comments about South Africa player AB de Villiers ahead of the third and final Test, which starts in Cape Town on Saturday. Warner today admitted the offence and accepted the proposed sanction offered to him by Roshan Mahanama of the Emirates Elite Panel of ICC Match Referees. As such, there was no need for a formal hearing. The charge related to comments made by Warner on Tuesday during an interview on Australian radio.
