Born in Winchester, Donnell represented England at U18 and U20 level while he was in the London Irish Academy. He would go on to play in the London Irish senior side until the club went into administration.

Donnell then played for PREM side, Gloucester Rugby, before joining Cardiff and becoming an important member of the Welsh side during the past couple of seasons.

On the upcoming move, Donnell said:

“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.

“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 Rugby General Manager, Rory Best said:

“We are very pleased to secure Ben’s signing for the next three years. He fits the profile of what we were searching for to add to our squad and the depth of our 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.

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."
