Leinster's finest import Isa Nacewa is set to leave the province at the end of the season as he retires from rugby for the second time.
The 35-year-old joined in 2008 and won 182 caps in two spells with the Blues, winning three Heineken Cups, a Challenge Cup, and a PRO12 title.
Nacewa decided to call it a day in 2015 and promised he would not play for another club due to his love for Leinster.
While working for Auckland Blues as a mental skills coach, the Fijian got the call from Leinster asking him to return in 2015 and he reversed his retirement decision to sign a one-year contract.
Nacewa will be joined by South African-born hooker Richardt Strauss who has won two Heineken Cups, a Challenge Cup and two PRO12 titles with the province while collecting 154 caps.
The 32-year-old also went on to represent Ireland on 17 occasions including three appearances at the 2015 Rugby World Cup.
The duo, together with recently retired number 8 Jamie Heaslip and the Ulster-bound back row Jordi Murphy, will be acknowledged by the club at the end of season Awards Ball this evening as Cullen also confirmed that Cathal Marsh and Peadar Timmins would be leaving the club at the end of the season.
"It is hard to articulate the impact that both Isa and Richardt have had on this club since their arrival.
"Warriors on the pitch and wonderful men off it, they are, in my opinion, two of the best players to have ever worn the blue jersey. Their impact on this group of players will be felt for years to come."
