Saracens have confirmed that back-rower Sean Reffell will be leaving the club at the end of the ongoing season.
The openside flanker made his professional rugby debut with Saracens in 2019 and has gone on to make 39 appearances for them after graduating from their academy.
The 23-year-old also was named the Young Player of the Season during Saracens' Championship campaign in the 2020/21 season.
He will now head to Irish province Ulster Rugby ahead of the 2022/23 season.
“I am incredibly grateful to the club for all the help and opportunities they have given me over the years. From the staff to the players there is a great environment which I have really enjoyed being a part of," said Reffell to the club's official website.
"I am excited for the future at Ulster and to get stuck in to the challenges ahead.”
Saracens director of rugby Mark McCall wished Reffell good luck for his future with Ulster.
“Sean is a player that we are sad to say goodbye to but, of course, we wish him all the best for the next part of his career at Ulster.”
Saracens are positioned second in the Gallagher Premiership table after managing seven wins from 10 games and will face Northampton Saints next on Sunday.
