Munster announced that Paul O'Connell will undergo surgery to correct the back problem that has him sidelined in the recent past.
A statement issued read. "Following consultation between IRFU and Munster medical staff and the player himself, it has been decided that Paul O'Connell will undergo back surgery at the earliest opportunity."
The former Lions captain is now likely to be sidelined for around eight weeks according to reports, ruling him out of Ireland's opening matches in next year's Six Nations championship.
O'Connell has only made two appearances for Munster this season, against Edinburgh and Racing Métro in the Heineken Cup, whilst also missing the November Internationals.
