Kieran Paul Treadwell (born 6 November 1995) is a professional rugby union player who plays as a lock for United Rugby Championship club Ulster. Born in England, he represents Ireland at international level after qualifying on ancestry grounds.[1]
Born in Sutton, south London, he attended The John Fisher School. His mother is Irish, and he represented Ireland at under-18 level.[2] He joined the Harlequins academy ahead of the 2014–15 season, and made his senior debut for the club in 2014.[3] He had a dual registration deal with London Scottish, for whom he played in the 2015–16 British and Irish Cup.[4] He played for England at under-20 level, and was part of the team that won the 2015 Six Nations Under 20s Championship.[5]
He moved to Ulster ahead of the 2016–17 season.[6] He played regularly in his first season, thanks to the absence of Alan O'Connor and Peter Browne with injuries, and the departure of Dan Tuohy to Bristol Bears,[7] making 21 starts and winning 47 lineouts.[8] He was named by Joe Schmidt in the Ireland squad for their 2017 Summer Tour.[9] In 2017–18 he made 23 appearances, including 19 starts, and made 155 tackles.[10] In 2018–19 he established himself in the team alongside Iain Henderson, making 28 appearances including 22 starts, and 235 tackles.[11] In 2019–20 he made 19 appearances, including 11 starts.
In 2020–21 he made 18 appearances, including 13 starts, and 149 tackles,[12] and made his 100th appearance for the province in February 2021.[13] Having not made an appearance for Ireland since 2017, he was called up for the 2022 Six Nations Championship,[14] and scored his first international try for Ireland in a 57–6 win over Italy.[15] In the 2022 tour of New Zealand[16] which Ireland won, Treadwell played in all three tests, and in both non-test matches against the Maori All Blacks. In the 2023 Six Nations[17] Treadwell helped Ireland win a Grand Slam by playing against his country of birth, England. He made his 150th appearance for Ulster against Connacht in December 2023.[18]
