Leinster will say goodbye to Ireland international Mike McCarthy at the end of the season, with the veteran second row set to join French outfit Narbonne in the Pro D2.
The move, which was first reported in last week's Irish Independent, will see McCarthy move on from the RDS after four seasons in blue, having joined from Connacht in 2013.
He has agreed a two-year deal with the French side.
“I have loved my time in Leinster Rugby and am very grateful for my time here," McCarthy told the club's website.
“But this is an excellent opportunity for me and for my young family and I am really excited for the challenge with Narbonne. There is a lot of ambition among the president and coaching team to rebuild this historic club and I’m really looking forward to playing a part in achieving this.
“However, firstly I’m focused on a big end of season with Leinster and hopefully repaying the club and the supporters with some silverware. We are in a really good place on two fronts and I look forward to contributing over the next few months and finishing out as strongly as possible.”
Leinster have already announced McCarthy's replacement, with Australian international Julian Fardy set to play second row for the province next year.
