Former Ireland captain and two-time Six Nations winner Claire Molloy has announced her retirement from international rugby at the age of 33.

The flanker made the announcement this afternoon on Twitter, saying she had experienced "priceless highs and rock-bottom lows" in her 12-year international career.

"12 years in the green shirt, not the ending I would have wanted," Molloy wrote. "So many memories, priceless highs and some rock bottom lows.

"To all the coaches, physios, team managers, S&Cs and all the backroom staff, thank you for guiding me along the way and often patching me back together at times.

"To the players I've shared the pitch with, it's been an honour. So many fantastic inspiring women I get to call friends.

"To my best supporters, my Mum and Dad, thank you for following me all over the world to watch.

"74 and out."

Molloy, a former inter-county Gaelic footballer for Galway who switched codes while studying medicine at Cardiff University, made her international debut in 2009, earning 74 caps over the next 12 years.

She was a member of three Ireland World Cup squads in 2010, 2014 and 2017, and was part of Ireland's victorious Six Nations winning campaigns in 2013 and 2015, the former a Grand Slam season.

Molloy was a member of the Ireland squad which reached the World Cup semi-finals in 2014 and was named Ireland's Player of the Year in 2012 and the Guinness Rugby Writers' Player of the Year in 2017.

She opted out of the Ireland set-up at the beginning of 2020 to concentrate on her medical career, though returned following the Covid-19 disruption.

Prior to embarking on her rugby career, she played for Galway in the 2005 All-Ireland Ladies football final, which they lost to Cork, winning an All-Ireland minor title in the same year.
