In that match, flanker Jean Deysel was sent off for stamping on Jordan Taufua's head and in the second half Willem Alberts was sinbinned. But despite the numerical advantage, the Crusaders failed to breach the Sharks' defence, the visitors holding on for a deserved 30-25 victory.
There will be a resolve among Blackadder's men to banish the memories of that night with a victory which would take them to their first Super Rugby final since 2011, the year of the earthquakes and constant travel which ended in defeat against the Reds in Brisbane.
For the Chiefs, it is a disappointing end to a season which started with so much promise - and a victory over the Crusaders in Christchurch. They have failed in their bid to join the Crusaders on three consecutive titles, a powerful Brumbies team streaking to a 22-3 lead following Tim Nanai-Williams' sinbinning, before the Chiefs began one of their traditional comebacks.
"We were uncharacteristically poor, they seemed shellshocked," coach Dave Rennie said of the Chiefs. "They seemed to be able to slice through us, we didn't belt them, didn't have that physicality.
"We did claw it back and the game was there for the taking, but we got trapped down our end.
"It's incredibly disappointing."
Former Waikato wing Henry Speight was a major thorn in the Chiefs' side. His powerful running cut the visitors open in the first half and they couldn't quite make up the deficit. The defeat means players such as Tanerau Latimer, Mahonri Schwalger and Asaeli Tikoirotuma will leave on a disappointing note.
The Highlanders will be happier with their efforts.
"I think we can be proud of what we achieved, especially tonight; one bounce of the ball and we could have been in Sydney next week playing the Waratahs," assistant coach Tony Brown said.
