It was immediately after Fraser's off-side goal. Whilst some of our players were busy complaining about the off-side to the ref and lino, Porteous was trying to re-start the game with a quick free kick, as several of our players out of position and not paying attention.
Mara saw this and "brushed passed" Porteous (ahem, perhaps there may have been an elbow to the body or suchlike). Porteous went down like a sack of spuds and the quick free kick was thwarted. Their goalie, who'd seen it all then started having a tantrum like a toddler who'd been told he wasn't allowed any more ice cream, cos the ref and lino weren't looking.
