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”.


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