The surgery nearly certainly rules O'Brien out for Ireland's opening game of the Six Nations against France in Paris on February, and given the nature of the injury so far, it's unclear as to how long it will take for him to get back to full fitness, athough Leinster have said that the aim, at least, is for him to return at some point during the tournament.

"Seán O'Brien saw a specialist this week for the tightness in his hip as it hadn't responded to treatment as we would have liked", the province confirmed.

O'Brien, therefore, looks set to miss Ireland's Six Nations opener in France on 3 February but could return later in the tournament.

"As a result he had a small procedure and the target is to have O'Brien back available during the Six Nations window".

The Leinster man has had an operation on the hip injury which has kept him on the sidelines since the Champions Cup clash with Exeter in the middle of December.

Leinster head coach Leo Cullen will speak to the media at lunchtime, where more detail on O'Brien's potential availability to Joe Schmidt and Ireland will become apparent.

Leinster say a return to play timeline for Byrne, who hasn't played since making his worldwide debut against Argentina in November, will be formalised post-surgery.

Meanwhile, Adam Byrne's comeback from a knee injury has received another setback after it was confirmed the winger will have a procedure today in a bid to fix the damage.
