Toulouse had been pencilled in as the other team for the Millau clash, but their Top 14 success has meant a change in the champions' pre-season schedule and they are not available to play on August 10th.
In their place the new Italian Pro 12 and Heineken Cup franchise, Zebre, have been lined up in their place.
The date and location of the game remain the same; Millau, France, on Friday, August 10th. The kick off time will be confirmed closer to the time.
