The England opener was caught behind at the slips but replays showed that the ball didn't touch his bat at all.
Unfortunately for Roy and England, the side was out of reviews after his opening partner Jonny Bairstow had wasted one on a routine LBW decision earlier, leaving Roy incensed as he walked off the field.
Roy, who struck a belligerent 85 in England's successful run chase, was found to have breached Article 2.8 ICC Code of Conduct for Players and Player Support Personnel, which relates to showing dissent at an umpire's decision in an worldwide match. The good news is, Jason Roy has forgiven and forgotten, as he and Dharmasena shared a hug before the match began. "He won't face any suspension".
However, the umpire also holds an unwanted record involving England. In 2016, during a Test in Chittagong, eight of his on-field calls were overturned, notably including a streak in which he gave Moeen Ali out three times in six balls, only for the batsman to successfully review each decision.
He will be featuring in his second consecutive World Cup final.
"If you had offered us the position to play in a final the day after we were knocked out of 2015 World Cup, I would have laughed at you", the Irishman said. The England star, 28, was fined 30 percent of his match fee for showing dissent and received two demerit points from match referee Ranjan Madugalle.
Dharmasena will be joined in the middle by Marais Erasmus, who stood alongside him in Thursday's semi-final. Rod Tucker will be the third umpire and Aleem Dar the fourth official.
