Edwards has been working with the London Irish squad since the start of the season, one day a week, but will not have any further imput ahead of the tournament matches against Mont de Marsan at Stade Guy Boniface and at home at the Madejski Stadium against Bordeaux-Begles nine days later.
"After consultation with Roger Lewis, CEO of the WRU, I am to concentrate solely on Welsh rugby in the build-up to Rugby World Cup 2015," Edwards said.
"Thus my consultancy work will cease with immediate effect."
Edwards was left out of the British & Irish Lions coaching staff for this summer's tour to Australia and will now concentrate on the Welsh side going into next months' RBS 6 Nations and the summer tour to Japan.
