Leinster have confirmed that 15 players have signed new contracts, to stay with the province into next season and beyond.
New deals for Jamie Heaslip and Devin Toner had already been announced in recent months.
However the province have also signed up 13 more players for the 2017/18 season.
Adam Byrne, Jack Conan, Dan Leavy, Luke McGrath, Jordi Murphy, Noel Reid, Mick Kearney and Richardt Strauss are among the names to sign up for at least another season at the RDS.
Bryan Byrne, Ed Byrne, Barry Daly, Tom Daly and Ian Nagle have also agreed new contracts.
Head coach Leo Cullen has been speaking to www.leinsterrugby.ie about the new deals:
"Only a few weeks ago we were able to confirm the promotion of seven players from within our own Academy to the Senior squad”.
“The news today of the retention of a further 13 players to the Leinster roster is a huge boost as we look to build towards next season.
"You need to have a strong squad capable of challenging on two fronts.
"We have used 51 players so far this season in the Guinness PRO12 and the Champions Cup and with 14 players capped during Ireland's 6 Nations campaign it is vitally important that we have that level of competition and experience across the squad at all times to try to maintain consistency in both competitions.”
Today's news is a further boost to the province, who have also signed Australian international Scott Fardy and Maori All Blacks winger James Lowe for next season.
"We are trying to play a brand of rugby that excites people and we want to give those supporters in the RDS or in the Aviva Stadium something to really get behind.
"The signings of Scott and James as well as the other lads that we have promoted to the Senior ranks and that we have retained is, I hope, a sign of where we want to bring Leinster next season and into the future.”
