South African-born, but qualifying for a Luxembourgian Passport, Jordan Sesink-Clee is a former student of the prestigious Michaelhouse School, an institution renowned for its ability to churn out Super Rugby starters. He formed part of a dominant 1^st XV who played at an intense speed and looked to distribute rather than take contact. This suited Sesink-Clee perfectly, as his handling and athleticism set him apart from other locks of his age. So impressive was the youngster that he was selected for the Sharks U18 Craven Week team; completely dominating the lineout and earning a junior contract with Western Province.

He later enrolled at Stellenbosch University, where the gifted set-piece general used his intellect to study Entrepreneurship and Innovation, whilst also turning out for a dominant Maties team in a title-winning Varsity Cup campaign. Despite the depth of talent in the WP ranks, young Jordan established himself as a consistent starter in their Supersport Rugby Challenge team, taking to senior professional rugby with ease and making the number 5 jersey his own. With the size to overpower opponents, and the skillset to outsmart them, it came as no surprise when the Sharks drafted Jordan into their 2020 Super Rugby squad.
