The recruitment process will be conducted in collaboration with the IRFU ensuring that the best possible candidate is secured. Leinster CEO Shane Nolan has confirmed that the process is already underway, highlighting the urgency and importance of this transition.

Cullen’s Future and Final Season

Reflecting on his decision, Cullen expressed his commitment to honoring his contract and ensuring a smooth transition. “I’m committed to Leinster up until the end of next season, and I intend to honor my contract, as I always have done,” he stated.
