Incoming Ireland defence coach Andy Farrell has taken up an advisory role for Pro12 side Munster with immediate effect.
It was revealed last week that Farrell has agreed to join Six Nations champions Ireland's coaching staff on a four-year contract ahead of their tour of South Africa.
Farrell was deemed surplus to requirements in a new-look England set-up under Eddie Jones, after head coach Stuart Lancaster's reign ended following a dismal Rugby World Cup campaign.
The 40-year-old will assist Munster head coach Anthony Foley over the next four months before starting work with Ireland.
Munster chief executive Garrett Fitzgerald said: "We have been looking for additional support for our coaching staff and with the timely availability of an experienced coach such as Andy Farrell we felt his inclusion would be hugely beneficial in assisting our coaching team."
Irish Rugby Football Union (IRFU) performance director David Nucifora said: "Andy's gardening leave prevents him from coaching in the international game at this time but he has agreed to an advisory role working with Anthony and his backroom team."
