Saracens have lured yet another South African opponent up to London to face them in November at Allianz Park, after the conclusion of the Currie Cup.
The Blues Bulls last week confirmed that they too would play Saracens in late January 2015.
This comes after the 2013/14 Premiership league winners, defeated the Sharks earlier this year.
The Saracens will be aiming to maintain their 100% record against top South African opposition.
Western Province Director of Rugby Gert Smal said: “To play Saracens in London will be a great experience for our players and coaches.
“While some of our players will be involved in the Springbok tour to Europe, we will field our strongest possible team at Allianz Park.”
Mark McCall, Saracens’ Director of Rugby, commented: “Western Province have long been one of the leading teams in the southern hemisphere, and it will be a great thrill for our players and supporters to welcome the Cape team to Allianz Park.”
Sarries topped the overall standings in the 2013/14 Premiership, losing just three times in 22 league matches, before going down narrowly to Northampton Saints in a dramatic final at Twickenham at the end of May.
