In short:
Australian referee Shaun Evans made an “OK” symbol below his waist during a live World Cup cross.
The symbol is used as both a harmless children’s game and as a white power symbol in some far-right circles.
FIFA’s discrimination monitor Fare called for Evans to be removed from the World Cup but the disciplinary committee “found no evidence of breaches of the FIFA disciplinary code”.


Was he stimming?
I think it looks very much like he was doing the ‘circle game’ thing, though he denies it was intentional at all.
