Ulster Rugby have announced that Ireland and current Leinster backrow Jordi Murphy will join the province next summer on a two-year deal.
Murphy becomes the second significant Irish signing for next year, with the news that former Leinster front row Marty Moore also joining, from Aviva Premiership side Wasps.
"It's been an incredibly hard decision to leave Leinster, where I have made some great friends and enjoyed some fantastic times, but I am excited by the prospect of moving north and linking up with some familiar faces," said Murphy who won the last of his 18 international caps for Ireland against Fiji last month.
"Having considered my options at length, I realise that this represents a great opportunity for me to challenge for a position at Ulster and hopefully become a more regular feature in the national set-up.
"Ulster is building a strong squad for next season and I'm really looking forward to the new challenge. However, I am fully focused on contributing as best I can for Leinster for the remainder of the current campaign."
The move will surely help his chances of nailing down a place for Ireland at the 2019 Rugby World Cup in Japan with Leinster's fully stacked backrow including with the likes of Sean O'Brien, Jack Conan, Rhys Ruddock, Josh van der Flier and the injured Jamie Heaslip.
