Keynan Knox (born 6 April 1999) is a South African rugby union player who plays as a prop for Pro D2 club USON Nevers.
Born in South Africa, Knox attended Michaelhouse, a boarding school where Springboks such as Ruan Combrinck, Ross Cronjé, Patrick Lambie and Pat Cilliers, and South African-born Ireland international Robbie Diack and former Munster player Pat Howard also attended.
Knox captained Michaelhouse's first XV rugby team during 2017, and featured for the Sharks provincial side during the under-18 Craven Week (also in 2017), where his set-piece and general play impressed.
On the back of strong performances at school level, Knox caught the attention of then-Munster CEO Garrett Fitzgerald, and he moved to Ireland upon finishing school to join the provinces academy setup in December 2017. He featured in all five of Munster A's fixtures during the 2018âÂÂ19 Celtic Cup, and signed a three-year contract with the province in February 2019, which saw Knox complete year three of the academy before progressing to the senior squad.
Because Knox joined Munster's academy before 31 December 2017, he qualified for Ireland based on residency in 2020, as this was before World Rugby changed the residency period a player must serve before qualifying for a country from three to five years. He made his senior competitive debut for Munster on 28 September 2019, featuring as a replacement in the provinces opening 2019âÂÂ20 Pro14 39âÂÂ9 win against Welsh side Dragons in Thomond Park, and he made his first start for the province in their 33âÂÂ23 win against Cardiff Blues on 2 November 2019.
Knox scored his first try for Munster in their 31âÂÂ17 win against Italian side Benetton in round 16 of the 2020âÂÂ21 Pro14 on 19 March 2021, and made his Champions Cup debut for Munster in their 2021âÂÂ22 pool B round 2 fixture at home to French club Castres on 18 December 2021, coming on as a replacement for John Ryan in the province's 19âÂÂ13 win. Knox signed a two-year contract extension in January 2022. He featured off the bench in Munster's historic 28âÂÂ14 win against a South Africa XV in Páirc UàChaoimh on 10 November 2022.
On 14 February 2024, Munster Rugby announced that Knox had completed his contract and would be leaving with immediate effect.
