Connacht and the Irish Rugby Football Union have announced the signing of Leinster second-row Ben Marshall, who joins from next season.
The 24-year-old lock or back-row forward is a graduate of the Leinster Academy and has enjoyed a breakthrough to the senior team, earning 10 of his 20 senior caps this season, including an appearance in the Champions Cup semi-final defeat away to eventual champions Toulon.
A mainstay in the Leinster 'A' side before he transitioned to the senior side, Marshall also has 10 Ireland U20 caps.
"The opportunity to join Connacht is one that I am very much looking forward to," he said.
"The ambition excites me and I can't wait to get started and to add to the mix. They have a good selection of second rows already but I look forward to putting my hand up for selection.
"I played in The Sportsground a few years back and it's not unlike the RDS Arena in many ways. The supporters are right on the pitch and it makes for a brilliant atmosphere. I'm looking forward to running out there and having them with me for a change!"
Connacht head coach Pat Lam added: "It's great to have someone with Ben's versatility joining our squad next season. He is a young player whose talent has already been recognised internationally as highlighted by his inclusion in the Ireland squad for this week's game against the Barbarians and also the Emerging Ireland squad.
"I have no doubt that he will fit in well within our culture and make the most of the opportunity to continue his growth and compete for a starting spot up front."
