The Wasps flanker's future in the game is already in the balance following media reports about drug-taking and dealing. Fresh allegations of cocaine use by the former England captain emerged this weekend, but Wasps say they have found no evidence to support the claims. Dallaglio described the allegations in a Sunday newspaper as "outrageous lies" and is contemplating legal action.
Simon Crane, the Wasps chief executive who is leading the club's investigation, said: "To date, it is quite clear from those we have spoken to, including some third parties, that they did not witness any illegal activity involving drugs."
The claims centred around a Wasps party at Harvey's bar in south-west London five weeks ago. Wasps, however, claim the two people making the allegations, a man and a woman, gave different names to the newspaper to the ones they were known by at the bar, and left their jobs before the article was published.
The Ireland coach, Warren Gatland, will not be taking action against the prop Peter Clohessy for his stamping on Australia's Ben Tune during Saturday's Test in Brisbane.
"I've had a bit of a chat to him, but that's about it," Gatland said. Clohessy was shown a yellow card for holding the Wallaby scrum-half George Gregan while in an offside position.Reuse content
