The last time the Crusaders lost to an overseas-based team in Christchurch was in February last year.
The Rebels were triumphant on that occasion, winning 20-10 at AMI Stadium despite losing halfback Nic Stirzaker to a yellow card in the second minute and being in the possession of a very ordinary record in New Zealand.
In the end they won convincingly, the Crusaders unable to score a point in the second half. The red and blacks don't lose to foreign teams at home often, but when they do they fall badly.
The time before that was in May 2014 when they lost to the Sharks 30-25 despite Jean Deysel's red card after 16 minutes and a yellow card to Willem Alberts in the 63rd, a bumbling performance from the home side which caused a fair bit of soul-searching about their conservative tactics.
All of which should have Todd Blackadder's men on red alert for tonight's match against the Jaguares.
