West Indies fast bowler Jayden Seales was fined 15 per cent of his match fee for his send-off to Australia captain Pat Cummins in the ongoing first test, the ICC said Thursday.
One demerit point has also been added to Seales's disciplinary record, according to the International Cricket Council, which said it was his second offence in a 24-month period.
The latest incident happened on the opening day of the match in Barbados on Wednesday when Seales gestured in the direction of the pavilion after dismissing Cummins for 28.
Afterwards Seales said his actions "did not really mean anything".
The 23-year-old however admitted the offence and accepted the sanction, the ICC said.
The test at Kensington Oval is finely balanced, with Seales taking 5-60 to help dismiss the visitors for 180 in their first innings.
