The ERC have confirmed that this season's Amlin Challenge Cup final will be played on Sunday, 23 May, with two possible venues.
Connacht play Toulon in their semi-final at the Sportsground this Friday and should they win and progress to the final, that match will be held in Kingsholm, Gloucester.
However, should Toulon win the final will instead be played in Stade Velodrome, Marseille.
The outcome of the other semi-final between London Wasps and Cardiff Blues will have no bearing on the final venue.
