The 2015 London Double Header was moved from its traditional Round 1 position, to Round 5, in order to accommodate the
2015 Rugby World Cup knock-out stage matches being played at
Twickenham Stadium. It was also the first time since 2005 that
Saracens,
Harlequins,
London Irish and
Wasps have not all taken part in the event. Harlequins chose not to take part due to the proximity of
The Big Game 8 and were therefore replaced by
Worcester Warriors. There had been suggestions that Wasps would not take part, following their move to the
Ricoh Arena, however they were announced as one of the away teams for the event at the fixture launch on 3 July 2015. ==2016==
