Joe Cullen says opponent Mensur Suljovic’s slow style of play is akin to cheating after the 32nd seed was knocked out.
Austrian Suljovic denied using any specific tactics in his second-round success.
“I never ever do this as a provocation,” said the 53-year-old. “I do it only for my game. Sorry Joe, I never do this – love you man.”
England’s Cullen won the first set, but became the 11th seed to crash out as he lost the following three, including throwing away a 2-1 lead in the fourth set.
Referring to the way that Suljovic slowed down play, Cullen said in a post on X: “If that’s darts, I don’t want no part of it.
“Always liked Mensur away from the board but that was plain for all to see! I don’t think I’m alone in feeling this way. The old guard will say it’s part of the game but word it how you will – it’s cheating. That’s not darts.”
After the match, the 36-year-old shook his head as he picked up his darts case and turned to glare at the Austrian, who celebrated his win in front of the crowd.
The PDC does not have a specific, timed rule for pace of play, but deliberate slow play intended to disrupt an opponent is considered unsportsmanlike conduct and a potential rules breach.
Suljovic is next in line to take on defending champion Luke Littler, who faces David Davies on Sunday evening.
Meanwhile, 2018 champion and 17th seed Rob Cross managed to avoid a deciding set against Ian White as he won a nervy encounter 3-1.
Krzysztof Ratajski beat Ryan Joyce 3-1 to reach the third round, while Luke Woodhouse cruised past Max Hopp with a victory in straight sets.
