Between 2012 and 2019, the 42-year-old right armer played three Tests, 58 One-Day Internationals, and 14 Twenty20 Internationals for Ireland.

Middlesex signed Murtagh from Surrey in 2007 and he has taken 951 wickets in 263 first-class matches.

It has been a pleasure to live out my childhood dreams for so long,” he said.

In 2016, Murtagh took 43 wickets at an average of 28.53 to help Middlesex win the County Championship title.

The north London club also won the T20 Cup in 2008, and he was a member of the sides that won promotion from Division Two in 2011 and 2022.

This season, Murtagh has been a player-coach for Lord’s, featuring in five of their 12 Division One matches. The club will offer him a full-time coaching position when he retires.

“Playing for this great club since 2007 has been an incredible honor for me, and I am grateful to everyone who made me feel right at home,” he said.

As I move into the coaching staff and the next phase of my life, I am excited to help the next generation of Middlesex cricketers live out their dreams.”

In his final Test appearance, Murtagh took 5-13 against England at Lord’s as the tourists bowled out the hosts for 85 before lunch in July 2019, Ireland’s first-ever Test match.

The average of his 13 Test wickets was 16.38.

Middlesex’s home Championship match against Warwickshire begins on Tuesday, and Murtagh is in the squad.

As Middlesex finish their red-ball campaign away at Nottinghamshire (26-29 September), it will be his 91st and final appearance at Lord’s.
