Whatever the outcome of the investigation and whether the four players involved are guilty of any crime or not, the simple fact that they put themselves in a position where they might be subject to such allegations shows at best a serious lack of judgement on their part and, at worst, demonstrates a level of unprofessionalism and irresponsibility that is totally unacceptable.
Rob Andrew says publicly that those players involved retain the support of the squad and the management. Privately I hope he has more than a few choice words for them.
I can only think that Martin Johnson will be sat at home seething at this news. Whether or not the names of the players are ever made public I suggest we keep an eye on omissions from the 32-man elite player squad, to be announced on 1st July, for clues as to their identities.
