Darts legend Phil Taylor walked off during a semi-final match after spectators made fun of his weight.
The 15-times world champion was playing Raymond van Barneveld at the Shetland Masters on the Scottish island when the incident happened.
'The Power' has lost two-and-a-half stones in recent months after changing his diet and said afterwards that he felt he took a necessary step.
"I want fans to come to the events and to enjoy themselves," he told the Daily Telegraph.
"It's fine for them to support a particular player, but it goes too far when the abuse is personal.
"I was upset by some of the comments being aimed in my direction, which was why I left the stage, and I apologise to the majority of fans that I wasn't able to finish the game."
A fan amongst the 700-strong crowd told The Sun about the incident that so enraged Taylor.
"He (Taylor) was getting dog's abuse from fans who obviously wanted Barneveld to beat him.
"Somebody shouted something from the crowd and Phil just walked off.
"The abuse he was getting was terrible, some of the people shouting were obviously drunk."
