South Africa captain Faf du Plessis was fined 50 per cent of his match fee for misconduct during his side's final group phase match in the World Twenty20 against Sri Lanka, an International Cricket Council (ICC) statement said on Tuesday.
South Africa won the match by eight wickets here on Monday. Both teams failed to qualify for the last-four stage.
Du Plessis was found to have breached Article 2.1.5 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".
This is the second time within a 12-month period that du Plessis has been found guilty of the same Level 1 breach. In October 2015, he was fined 15 per cent of his match fee for violating Article 2.1.5 during the fourth One-Day International against India in Chennai.
The incident happened in South Africa's 13th over when du Plessis, after being given out leg before wicket (LBW), showed dissent at the decision by occupying the crease for a period of time before leaving the field while looking at his bat and shaking his head.
After the match, du Plessis admitted the offence and accepted the sanction proposed by match referee Jeff Crowe. No formal hearing was done.
The charge was levelled by on-field umpires S. Ravi and Rod Tucker, third umpire Paul Reiffel and fourth official Chris Gaffaney.
