Hougaard played for Western Province in 2007 before joining the Blue Bulls; he spent eight seasons at the Pretoria-based team, representing them in the Currie Cup as well as playing Super Rugby for the Bulls. Hougaard scored a try in the
Currie Cup final win 36–24 against the
Free State Cheetahs (3rd min) following a superb crosskick from
Fourie du Preez for his first final at 21 (the youngest player in the starting line) wearing the number 14 jersey. In the
2011 Super Rugby season, Hougaard showed great promise, adapting to his self-proclaimed preferred position of
scrum half in the absence of Fourie Du Preez, very well, and as a result, landed a position in the Springbok World Cup Squad for the 2011 tournament. At school he played for
Paul Roos Gymnasium. In February 2016, Hougaard signed a short-term contract with
English Premiership club
Worcester Warriors for the remainder of the 2015–2016 season. He made his debut for his new side in their match against
Sale Sharks, marking the occasion by scoring a try in a 31–23 victory and also put in a man-of-the-match performance in their 15–14 victory over the
Newcastle Falcons two weeks later. On 15 March 2016, it was announced that Hougaard signed a permanent contract with the team, but would be allowed to link up with the
South African sevens team to participate at the
2016 Summer Olympics in
Rio de Janeiro. Hougaard left Worcester Warriors to join Premiership rivals
Wasps ahead of the 2021–22 season. He was made redundant along with every other Wasps player and coach when the team entered administration on 17 October 2022. ==International career==
