Paul O'Connell has revealed that Sunday's 19-9 victory over England may have been his last Six Nations appearance in Dublin.
The Munster lock, who has won 99 caps for his country, claimed that any decision will wait until this autumn's Rugby World Cup, but the Irish captain conceded that it could have been his final Test at the Aviva Stadium.
He is quoted by Sky Sports as saying: "It could have been but I don't know yet, I'm undecided. I'll probably make the decision soon enough, I really want to play to the World Cup and be in the best shape I can there and see after that.
"That probably was my last Six Nations game against England in Dublin: there's no point kidding myself too much. I'm not trying to make a big deal by not saying anything, I just genuinely haven't decided what to do yet.
"I'm really enjoying playing at the moment in the set-up we have in Ireland, but I'm conscious we have a lot of good second-rows coming through as well. The World Cup is a big focus for me to try to go there and be in the best shape I can, and around then will be decision time for me."
Ireland will win their second Grand Slam in six years if they can beat Wales and Scotland in their final two Six Nations games.
