He joined the Golden Lions Currie Cup team for the 2016 season.[6]
He joined English Premiership side Sale Sharks prior to the 2017–18 season on a three-year contract.[7] In December 2018, the club announced that De Klerk signed a contract extension until 2023.[8]
After four seasons with the Sharks, de Klerk announced in June 2022 that he would be departing the club at the end of the 2021–22 season to join Yokohama Canon Eagles in Japan Rugby League One.[9][10]
International career
De Klerk was rewarded for his Super Rugby form when he was selected by the then recently appointed Springbok coach Allister Coetzee in South Africa's 31-man squad for their 2016 three-test match series against Ireland[11] and made his test debut as the starting scrum-half in the opening test at Newlands Stadium. In a tightly-fought series, Ireland won the first test 26–20, but the Springboks fought back to clinch the series, winning 32–26 in Johannesburg and 19–13 in Port Elizabeth.
After signing for Sale Sharks in 2017, De Klerk was ineligible to represent the Springboks due to having fewer than 30 caps.[12] However, after this selection criterion was abolished in 2018, new Springbok coach Rassie Erasmus recalled De Klerk to the team for the 2018 three-test match series against England.[12]
He was a member of South Africa's victorious 2019 Rugby Championship campaign and was duly selected for the 2019 Rugby World Cup.[13] In their 20 October quarter-final match against Japan, he was named Player of the Match.[14] He was a key player for South Africa's World Cup victory, being named as the starting scrum-half in two of their pool matches, as well as all their play-off games. He scored a try in their quarter-final win over Japan.[15]
De Klerk was once again included as the starting scrum-half against England in the 2019 Rugby World Cup Final, which saw South Africa beating England 32–12 to secure a third Webb Ellis Cup lift.
