Canada warned after 'F-bomb' Olympics curling exchange with Sweden
Sweden believed one of the Canadians was repeatedly double-touching, giving the stone another little prod with his finger to correct its course during Friday's round robin match.
Tempers frayed with Canada's Marc Kennedy and Sweden's Oskar Eriksson trading insults.
"I don't like being accused of cheating after 25 years on tour and four Olympic Games," said Kennedy.
"So I told him (Eriksson) where to stick it. He might have been upset that he was losing..."
Canada went on to win 8-6.
On Saturday, World Curling said it had spoken with the Canadian officials "to issue a verbal warning regarding the language used".
"It's an intense competition... the biggest stage of the world," Curling Canada CEO Nolan Thiessen said.
"Do I wish Marc didn't drop an F bomb? Wrong choice of words, but (it was in the) heat of the moment and we'll carry on.
"Probably poor choice of words. I think heat of the moment I would allow for as well. Something was said in his ear, which kind of got him going.
"I stand behind those guys. They always play with a lot of integrity, and they would never knowingly do anything that was offside from the rules."
"But it shines a little extra light on the sport. Sometimes that's not a bad thing."
World Curling said in a statement that video replay to re-umpire game decisions are not used and no violations had been recorded on Friday.
