Ellis Park, that bastion of South African rugby, is where the Crusaders will undergo a severe test of their spirit tomorrow morning.
And, if they do find a way to win against the Lions, who are unbeaten at their Johannesburg home this season, without their talisman Kieran Read, they will have to do it all over again the following week in Bloemfontein against the Cheetahs. Time is running out for Todd Blackadder's men, who have made it a habit of scrambling a victory first-up in the republic, and often against the odds, only to turn in a half-hearted performance a week later.
In 2011, a Crusaders team already missing injured All Blacks Ben Franks, Dan Carter, Richie McCaw, Brad Thorn, Sam Whitelock and Andy Ellis beat the Stormers 20-14, despite losing four backs - Israel Dagg, Kahn Fotuali'i, Sean Maitland and Adam Whitelock - in the first half.
The following week they lost 33-20 to the Cheetahs in Bloemfontein despite the return of Franks, McCaw and Carter.
Last year the Crusaders followed gritty away victories over the Sharks and Stormers with a shock loss to the Force in Perth. It cost them any chance of overtaking the Chiefs as New Zealand conference leaders.
