The province have disclosed today that O'Mahony will miss the rest of the season.
Peter O'Mahony is to undergo reconstructive shoulder surgery this morning and is ruled out for the remainder of the season.
O'Mahony travelled to Dublin late yesterday evening for a review with the specialist, and following the consultation it was confirmed that the Munster captain required surgery on his left shoulder.
Peter sustained the injury in the opening 20 minutes of Munster's 47-23 victory against Toulouse on Saturday after he over-extended his shoulder.
