Ireland's John Mooney and West Indies all-rounder Darren Sammy both admitted Level 1 offences for swearing audibly during Ireland's World Cup win over West Indies in Nelson on Monday.
Both players were fined 30 per cent of their match fees after Ireland secured a famous World Cup win by four wickets.
Mooney lost his temper when a catch was put down by one of his Irish team-mates, and former Windies captain Sammy voiced his irritation while batting.
Both players accepted the sanction. All Level 1 breaches carry a minimum penalty of an official reprimand and a maximum penalty of a 50 per cent match fee.
