think the rules are, if the ref said he saw it and delt with it, then there will not be retrospective punishment,
something like that i think.
if he didnt see it,. then there can be a review and ban
Judging by the ref and lino both kind of shaking their heads it looked like neither of them did see it. As the offense occured when play had moved over or on the halfway line I'm sure they didn't.
