Ronnie O'Sullivan was warned for making a gesture during the eighth frame of the World Championship final, the World Snooker Tour clarified in a statement.
Commentators and viewers were left bemused during the final frame of the first session of the match between O'Sullivan and Judd Trump at the Crucible, when referee Olivier Marteel went to speak to the seated O'Sullivan after he had just missed a shot.
Marteel's intervention prompted O’Sullivan to jab his finger and respond that the official “saw nothing”. O'Sullivan could also be heard saying "don't start" to Marteel, before Trump then appeared to question why his opponent's ticking off couldn't have waited until after the frame had finished.
