Cardiff forward Ben Donnell will join Ulster at the end of the current season on a three-year deal.
The versatile 25-year-old, who is Irish-qualified, can also operate in the second row or back row positions.
Donnell represented England at U18 and U20 level and had spells at London Irish and Gloucester Rugby, before joining Cardiff in 2023.
He has made 26 appearances for the Welsh side and has scored four tries to date.
“I’m really pleased to be signing for Ulster Rugby. With my family roots in Belfast, it makes the move even more special for me,” Donnell told the Ulster website.
“I am very excited by the opportunity to join a team that’s playing some fantastic rugby and are competing at the top end of the league.
“I know how tough Ulster are to play against, so I’m hugely motivated to come in, work hard, and add real value to a squad full of young talent and quality experience. I’m looking forward to getting started and pulling on the Ulster jersey.”
Ulster general manager Rory Best said that Donnell will add “depth” to Ulster’s forward pack.
“He is at a good age, with valuable experience from London Irish, Gloucester and Cardiff and that will bolster our squad and help drive competition,” Best added.
“Ben is a strong ball-carrier with the versatility to play in multiple positions, which is an important skillset to have in the modern game.”
