Mike Prendergast will swap Racing 92 for Munster Rugby in the summer as attack coach on a three year contract.
Prendergast, who had two spells at Munster as a scrum-half, has been on the province's wanted list since Johann van Graan and Stephen Larkham announced late last year that they will be leaving in the summer.
The Reds have now confirmed that Prendergast has agreed to leave his post as Racing's backs coach to take up his role alongside Munster's new boss in waiting Graham Rowntree from July 1.
