Ireland skipper Peter O'Mahony refused to rule out retirement after helping the Wolfhounds retain their Six Nations title by beating Scotland 17-13 in Dublin.

Andy Farrell's outfit struggled to pull clear in a close first half despite Dan Sheehan's try as Finn Russell converted two penalties to keep the determined Bravehearts within a point at the break.

But the Irish grew in confidence and were eventually rewarded when Andrew Porter went over but still had to overcome a nervy finish thanks to a late Huw Jones try.

They become just the third Ireland team to retain the Six Nations title, further cementing their names in the rugby history books.

After the win, O'Mahony spoke of his pride in playing for his country but refused to confirm if it was his final international appearance.

The flanker, 34, told ITV: "I don't know. If it was my last one, it was a pretty good one.

"Thankfully we went out and did it against a good team. We showed grit, ambition with the ball, and I thought we played some good rugby.

"We spoke about getting stuck in, and put a lot of work in their legs. I thought the 10 minutes after half-time was really impressive.

"It's a huge honour every time you get selected to play for your country."

Proud fly-half Jack Crowley, 24, was happy Ireland could deliver on their title defence and also praised O'Mahony for his leadership.

He said: "It's everything to win a trophy for the country. Representing this nation is something that we speak about a lot as a group.

"To win a trophy and be able to give something for all the support they have given us over the past couple of years — I'm delighted we could do that for them.

"He's [O'Mahony] unbelievable, isn't he? He is a leader and we follow him everywhere.

"We follow him into battle and he is someone we all have such high respect for. You will play for him every day."
