Veteran Cian Healy and current Ireland first choice scrum-half Jamison Gibson-Park have signed new deals with Leinster.
Healy, 34, has been a key member of the Blues' four Champions Cup titles and has played 241 times for the province.
Andrew Porter has taken the Clontarf man's starting place at loosehead for Leinster and Ireland but he provides vital cover for Andy Farrell and Leo Cullen respectively.
