St George Illawarra will join NRL rivals South Sydney and Brisbane in contesting next year’s World Club Challenge in England.

St George Illawarra have been added to the inaugural six-team World Club Series in February, it has been announced.

The Dragons accepted an invitation to join NRL rivals South Sydney and Brisbane in the expanded World Club Challenge tournament, which will be played in the north-west of England over the weekend of February 20-22.

Souths were confirmed before they won the NRL grand final on Sunday and they will meet the winners of Saturday’s Super League title decider at Old Trafford between Wigan and St Helens in the 2015 World Club Challenge.

The losers, along with Super League’s third-ranked team Warrington, will take on the Broncos and Dragons in the build-up to the World Club Challenge, although the final fixtures have yet to be determined.

St George Illawarra won the World Club Challenge in 2011 with a 21-15 victory over Wigan at the DW Stadium.

Dragons chief executive Peter Doust said: “The World Club Series is a great concept and something that our club has been an advocate of for some time.

“We are delighted to have been invited by the Super League and look forward to this inaugural event.”

Super League general manager Blake Solly said: “Having tasted success in the 2011 World Club Challenge, it is fitting the Dragons are the third representative from the NRL.

“The Dragons have a unique place in the history of the sport and Super League fans will look forward to seeing them in the series.

“With the Wigan Warriors, St Helens and Warrington Wolves confirmed as Super League’s participating clubs, excitement is already building for the series.

“Not only will the World Club Series pit club against club, but the Super League against the NRL is a fascinating competition between two leagues and two hemispheres.”
