I don't think they'll get any joy on that front - Martin stood over it for a while, then moved away and Harriman stood over it, at which point the ref waved a yellow. I don't think any argument about mistaken identity will hold up because while Harriman was the one standing over it at the time, it was Martin who had stood there for a while and done nothing, so the ref will say it's for the first offence, I guess.
Agree with that, but shouldn't the ref have called Martin towards him instead of brandishing yellow in front of Harriman with Martin five yards further away?
That's how I remember it happening.
