Gerwyn Price has been fined £21,000 and handed a three-month suspended ban following his behaviour at the Grand Slam of Darts.
The Welshman took part in an ill-tempered final against two-time Grand Slam winner Gary Anderson.
Anderson accused Price of slow play and exuberant celebrations – with the two confronting each other in the 15th and 28th legs.
Price went on to win the title 16-13.
He was also investigated over his antics when beating Simon Whitlock in the quarter-finals and warned about his future behaviour.
Scot Anderson received a formal warning.
