Vancouver Canucks superfans, the Green Men, are being asked to tone down their act at games after a complaint was filed with the National Hockey League.
Sully and Force, who wear full neon green bodysuits, have been asked to stop touching the glass and doing handstands.
The popular paying fans usually sit close to the Canucks' opponents in downtown Rogers Arena and their act has been described as a circus sideshow.
Hockey Night in Canada panellist Eric Francis says the fans haven't done anything wrong, don't interfere with players and add to the ambience of the stadium game.
Fans of the uber fans are now rallying for the Green Men on Facebook, as the Canucks continue their series tied 1-1 against the Nashville Predators in the Conference semi-finals. There's no confirmation on who filed the complaint.
Last week, the NHL cracked down on a Vancouver car dealership for posting "Go Canucks Go" signage in its window.
