South African skipper Faf du Plessis was fined Tuesday by the International Cricket Council (ICC) for showing dissent during his side's win over Sri Lanka at the World Twenty20.

Du Plessis was fined 50 percent of his match fee for "occupying the crease for a period of time" after being given out lbw (leg before wicket), before leaving the field while shaking his head in Monday night's match in New Delhi.

It was the captain's second fine for dissent in less than a year. He faces suspension if he commits a third offense before October, 12 months since the first, the ICC said in a statement on Tuesday.
