Sean O'Brien will miss Ireland's November internationals and could be out of the Six Nations as well after being ruled out of rugby for up to six months with a shoulder problem.
Leinster coach Matt O'Connor said Thursday the 27-year-old backrower would undergo an operation in London on Friday.
British and Irish Lions flanker O'Brien has an infection in the shoulder reconstructed after Ireland's dramatic 24-22 defeat by world champions New Zealand in Dublin last November.
