The potential knock on effect is that the semi final sale could potentially play in will have to be on a Sunday. As things stand that looks like 1 v 4 or Exeter v Bristol or Sale.
Given Sale are due to play on Wednesday, it'll have to be a Sunday game, which means Bristol have a Sunday to Friday turn around ahead of the Challenge Cup final and will lose a day traveling to France. You can understand why Pat Lam is fuming. I would be too.
