The 28-year-old South African has put pen to paper on a new deal with the region and will link up with the Scarlets ahead of the 2018-19 season from Guinness PRO14 side Cheetahs.
Cassiem, who has featured on eight occasions for the Springboks, started his playing career with the Golden Lions in 2011.
The ball carrying No 8 is the third new name added to Scarlets’ squad for the forthcoming season, alongside loose forward Blade Thomson from Super Rugby’s Hurricanes and centre Kieron Fonotia from the Ospreys.
Current internationals Aaron Shingler, Ryan Elias, James Davies, Rhys Patchell, Wyn Jones, Gareth Davies, Jake Ball and Jonathan Davies have put pen to paper on new deals with the Scarlets as well as Dylan Evans, Jonathan Evans and Lewis Rawlins.
Commenting on the news head coach Wayne Pivac said; “Uzair is a current international who possesses the skills that we believe will suit the way we play the game. He’s a dynamic player that likes to carry and has the ability to offload, is a very physical individual and has good aerial skills.
“He’s currently playing at the highest level of the game and faced Wales in the recent Autumn Series at number 8. He has the ability to play across the back row but has been signed primarily as an 8.”
Cassiem added: “The Scarlets are known throughout the world and are playing some great rugby at the moment. When I met with Jon and Wayne it was clear to see the ambitions of the club and the environment at the Scarlets is just what I am looking for.
“I’ll be giving my all for the Cheetahs for the rest of the season whilst looking forward to the next chapter of my rugby career in South Wales.”
