Rowan Osborne has left Leinster to sign a one-year deal at Munster ahead of the 2021/22.
The 24-year-old made 10 appearances for the Donnybrook-based side in the Guinness Pro 14 since making his debut in 2019.
The Kildare native secured his path to professional rugby in 2019 off the back of impressive performances with his club side Dublin University in the All Ireland League.
"I am delighted to be joining Munster next season, one of the biggest clubs in Europe with a great fanbase and history," said Osborne.
"I am hugely looking forward to working with and learning from a really talented group of players and a great coaching ticket and working hard to help bring success to the club."
Meanwhile, Ulster have confirmed that Jack McGrath had hip surgery last week and will now begin a period of rehabilitation under the care of the Ulster Rugby medical performance team.
