Ireland and Leinster flanker Sean O’Brien will join London Irish in December following the Worldcup.
It was reported that 31-year-old O’Brien was set for a move to the Championship leaders and the switch has been confirmed on Monday.
O’Brien will link at the club with Les Kiss and former Ireland head coach Declan Kidney.
He said:”I’ll roll up the sleeves and utilize my expertise to reestablish London Irish as a top club in England.”
“After talking to Declan it was apparent that the ambition London Irish have being a club,” added O’Brien, who is just a two-time British and Irish Lions tourist.
“It’s a club that’s been in existence for quite a while and there’s an obvious link with Ireland with some greats of Irish rugby having worn on the jersey.
The movement is unlikely as he is centrally contracted until the conclusion of the tournament to the RFU to affect O’Brien’s World Cup prospects.
O’Brien’s position is like Paul O’Connell before the 2015 World Cup – when the Irish captain had consented to combine Toulon.
But while there is no official policy about the selection of players located outside Ireland, it’s unlikely Andy Farrell, that can replace Joe Schmidt since Ireland head coach will considers for the 20 20 six-nations O’Brien.
Ireland Under-20 duo Conor Gilsenan and former Munster Fly Half Ian Keatley and Brendan Macken are currently on the novels of London Irish.
