After representing the Sharks in the 2006 Under-13 Craven Week competition, he moved to Ermelo and subsequently represented the Pumas at the 2009 Under-16 Grant Khomo Week and 2011 Under-18 Craven Week tournaments. His performance in the latter tournament led to his selection in the 2011 South African Schools squad.[2]
Du Plessis made his senior debut for the Blue Bulls in 2013, starting in the 110–0 thrashing of the Limpopo Blue Bulls.[4] He also started the game the following week in an equally impressive 89–10 victory against the Griffons,[5] a match that saw him score his first try, dotting down shortly after half-time.
In July 2013, the Blue Bulls announced that he signed a contract extension until 31 October 2015.[6]
