This is Leicestershire --The man who knocked out Toby Flood during Leicester Tigers' pre-season game against Ulster will not face a citing or any punishment.
The Rugby Football Union (RFU) are powerless to pursue the matter due to an administrative technicality that they are keen to make sure never occurs again.
Tigers were extremely angry about the incident, which showed lock Dan Tuohy raising a forearm to Flood's face as the Leicester skipper tried to tackle him.
Flood was knocked out and left the field on a stretcher after a 12-minute delay in the game.
Director of rugby Richard Cockerill will now miss his main play-maker for at least Sunday's Aviva Premiership opener against Worcester and potentially longer.
"There are concussions within the game but you have to stop people leading with their arm and smashing it through people's heads," said Cockerill after the incident at Welford Road last Saturday.
"The RFU are aware of it and it is for them to deal with. Whether they think that is foul play is up to them."
But the RFU said they can instigate no further action because Irish province Ulster did not go through the process of signing a particular form before kick-off, which meant the game would have come under RFU jurisdiction. Had the game taken place between two English teams, it would be up to the RFU's disciplinary department to cite any examples of foul play that could have led to red cards.
But when visitors from other countries play English teams on English soil, they must agree to sign over any post-game disciplinary action to the governing body of the home country.
Nothing compels a visiting team to take this action and, on this occasion, Ulster did not agree to it ahead of the fixture.
The RFU said this was a grey area in pre-game procedures and that they would be speaking to other countries' governing bodies to try to end a loophole that will see Tuohy get off without further investigation.
An RFU spokesman said: "Ulster players were not subject to the RFU's jurisdiction in this match and, as a result, no action can be taken.
"Clubs can agree how discipline should be dealt with in advance of such games and we're looking to see how we can make sure this always happens in the future." Reported by This is 14 hours ago.
