O’Mahony, 35, has won 112 Ireland caps since making his international debut against Italy in 2012. Last year, he took over as captain following Johnny Sexton’s retirement and led the side to the Six Nations title.
He was replaced as captain by Caelan Doris ahead of the November internationals, and while he was not in the squad for the opening Six Nations win over England, he started the defeats of Scotland and Wales.
The flanker has also won two league titles for Munster having made his debut in 2010. He was the province’s captain for 10 years before stepping down in late 2023.
O’Mahony featured in three World Cups for Ireland and toured with the British and Irish Lions in 2017, captaining the side in the first Test against New Zealand.
O’Mahony’s Munster team-mate Murray has won 124 Ireland caps since making his debut against France in 2011.
Sexton’s long-time half-back partner, 35-year-old Murray is a three-time Lions tourist (2013, 2017 and 2021) and temporarily took over as captain in 2021 during Alun Wyn Jones’ injury-enforced absence.
Like O’Mahony, Murray made his Munster debut in 2010 and has made 199 appearances for the club. While O’Mahony will hang up his boots after this season, the scrum-half will continue his career outside of Ireland, with details of his move not yet disclosed.
