Munster have confirmed that JJ Hanrahan will rejoin the province next season.
The Kerryman will return to Thomond Park after two seasons with Northampton Saints.
Munster have also confirmed the acquisition of scrum-half James Hart and centre Chris Farrell for next season.
Former Ireland U20s player Farrell, now 23, joins from Grenoble where he has been for the last three seasons. The Belfast-born player made 70 appearances for Bernard Jackman's side, scoring 10 tries.
25-year-old James Hart, a goal kicking nine from Dublin, joined Racing 92 this season from Grenoble. He has made 12 appearances for the Paris-based club.
Hanrahan, Farrell and Hart have signed two-year contracts with Munster.
Munster also announced contract extensions for Tyler Bleyendaal along with Dave Kilcoyne, Niall and Rory Scannell, Duncan Williams and Darren Sweetnam.
Kilcoyne's new deal runs until 2020 while the rest will be at Thomond Park until at least 2019.
Director of Rugby Rassie Erasmus was hugely positive about the signing of Hanrahan, Farrell and Hart.
I've always indicated our intention to recruit Irish qualified players where and when possible so to secure the young trio of Farrell, Hanrahan and Hart is great for the province and Irish rugby in general. In addition to being hugely talented they bring a wealth of knowledge with their combined experiences from playing abroad and this will help with our overall squad development.
Erasmus would appear to be building a real rapport with players at the club. While addressing the contract extensions, he referred to Kilcoyne and Sweetnam by their nicknames.
He added that these new deals are key to long-term success.
I've talked about maximising our potential time and time again. Retaining players such as Killer (Dave Kilcoyne), Niall, Rory, Tyler, Duncan and Sweets (Darren Sweetnam) is key to our long-term plans and they have all played an integral role in our success so far this season.
Developing home-grown players is at the core of everything we do and it's rewarding to see five players who have advanced from the Munster pathway commit their future to the club, while also recognising the efforts of Tyler who has overcome long-term injury to make his mark in the squad this season.
