I saw this on a comment section, which, although isn't a great source of information, sounds like its probably more realistic.....
"Truth is Kiernan was verbally abused by one idiot outside the Players Lounge. One of Kiernan's company reacted and a brief, noisy argument took place. Heat of the moment stuff and the balloon who had a go at big Rob was removed from the situation by his own mates. No stewards whatsoever were involved."
I never understand when players are berated in this manner off the pitch, its as though the abuser thinks that players go out each week with the mindset "you know what will be fun this week, i'll play sh*t to p*ss everybody off and it will be funny"
