Seb returned for a second spell at Newcastle Falcons in the summer of 2022, having helped the club to promotion during the 2019-20 Championship-winning season.

The 6 foot 7 former South African Under-20s international was raised in Johannesburg and has played for Leicester Tigers and London Irish in England as well as French club Mont de Marsan.

He re-joined the Falcons from American side Austin Gilgronis, having helped them to top spot in the Western Conference of Major League Rugby in 2022.

Making 24 appearances during the 2022-23 season, Seb was among the league’s leading line-out forwards, regularly appearing in and around the top of the charts for both steals and takes on his side’s own throw.

The 2023-24 campaign once again saw his importance to the squad underlined, making 21 appearances and scoring a pair of tries.
