Bristol number eight Ryan Jones will miss Wales tour of South Africa next month after undergoing surgery on his ankle.
Jones sustained the injury in Bristol's first leg of their Championship Final against London Welsh on Wednesday.
The 33-year-old suffered ligament damage during the first half at the Kassam Stadium, before going for an operation.
Bristol suffered a crushing 27-8 defeat in the first leg of the final, with the return leg on home soil taking place next Wednesday at the Memorial Stadium.
Carrying a 19-point deficit into the second leg is an enormous challenge for Andy Robinson's squad, who with an eye on the Premiership have already made a number of high-profile signings for next season including Jones, Jack Lam from the Hurricanes along with Dwayne Peel, David Lemi and Anthony Perenise.
