Scotland international tighthead joined Edinburgh Rugby ahead of the 2023/24 season from BKT URC rivals Scarlets.
Sebastian made his international debut against Japan in November 2021, with the prop’s father born and raised in the Scottish capital.
Sebastian is well known to Scottish rugby fans on the west coast, where the tighthead impressed while playing for Ayr RFC during a season-long partnership contract with Glasgow Warriors in 2015/16.
The Carmarthen product was part of the Scarlets academy and represented Wales at both U16 and U18 levels.
Following a stint at Scotstoun, Sebastian returned to Scarlets at the start of the 2017/18 season, making his then-PRO14 debut against Cheetahs in February 2019.
The prop enjoyed a breakout campaign at Parc y Scarlets in 2020/21 – featuring 17 times for the West Wales side, 10 as a starter.
That form earned Sebastian a call-up to the Scotland squad for Summer Test fixtures against England A, Georgia and Romania, all of which were eventually cancelled due to Covid-19.
The tighthead eventually made his international debut that autumn – coming on as replacement against Japan at BT Murrayfield – before featuring in two of three Tests against the Pumas in last summer’s tour to Argentina.
