Ben Te'o will leave Leinster at the end of the season and sign for English side Worcester Warriors.
The former rugby league star has played 23 times for Leinster, scoring five tries, since his move from the South Sydney Rabbitohs at the end of the 2013/14 season.
Te’o broke his arm on his debut against Edinburgh in October 2014 but went on to play a further 12 times last season including the European quarter-final clash against Bath and the semi-final defeat to Toulon.

Speaking about the cross-channel move, Te'o said: "Warriors are in a very similar stage in their playing and cultural development that I found when I first joined the Rabbitohs and I look forward to making a similar contribution at Sixways.
"The investment in facilities and infrastructure is impressive and after speaking with Dean Ryan, it is clearly a Club which is on the up. Everything is in place for Worcester to become a successful club competing in the top tier and I'm excited about getting started at Sixways.
"I'd like to thank Leinster Rugby for giving me the opportunity to go back to Union and to the fans for their support in particular when out injured. I look forward to finishing the season with Leinster as strong as possible."
Worcester are understood to have fought off strong competition for Teo's signature, a statement of intent as the Warriors continue their battle for top-flight stability.
"Ben is a really exciting talent and has proved he is more than capable of transferring his skills from league to union," boss Dean Ryan told warriors.co.uk.
"His experience and power in the centre will add further depth to our midfield and we're looking forward to him joining up with the side."
Leinster head coach Leo Cullen said: "Although disappointed that Ben is leaving, on behalf of everyone at Leinster Rugby, we would like to wish Ben the very best with his move to Worcester and indeed with his quest to play international rugby.
"Ben is a very popular player within the group and we believe that he can still play a big part in our season. He showed in his last season with the Rabbitohs that he has the skill set to apply himself brilliantly in delivering some big performances on the way to helping his club win the NRL title in the full knowledge that he was joining Leinster."
