Unfortunately for the Crusaders, they will do so without All Blacks' No8 Kieran Read, who suffered a rib injury in that recent round-robin victory over the Chiefs and hasn't played since.
Blackadder said Read had suffered "tiny stress fractures" in a rib which were healing well but will keep him out for at least another week.
"It is disappointing but I'm really happy with how our loose forwards are going. Richie [McCaw] in particular has been on fire lately."
McCaw, at No8 in Read's absence, is growing into the position by the week. Last night he appeared to be doing both his usual opensider's job plus that of a No8, so effective was he at the breakdown. Flankers Matt Todd and George Whitelock were also highly impressive against a Bulls' pack which in comparison lacked accuracy and intensity.
Throw in the fact that Dan Carter, who kicked 23 points, completely dominated his opposite Morne Steyn, who had a horror night, and the Bulls hardly stood a chance.
The Chiefs, rested and on home turf, will present a much bigger challenge. Blackadder is aware of that and the fact that their lineout probably won't be as bad as it was a couple of weeks ago.
"We've just got to be more clinical than last time. We played well but then let it slip, but to give them credit, they took their opportunities too ... We actually learned a lot from that game, we took a lot out of it.
"They will bring out some new stuff but I really back our set piece. We've been consistent all year there."
There is a resolve within the Crusaders' camp and a quiet belief that this could be their year. Their new stadium in Addington, which was about 4000 short of capacity last night (Sat) has eased the constant grind of travelling following last year's earthquakes, and they were deeply disappointed to lose to the Reds last year following their comprehensive semifinal victory over the Stormers.
There is even the slim chance of the Crusaders, who have made the semifinals of this competition every year since 2002, hosting a final if they and the Sharks win this weekend.
"The Sharks are a very good side - I picked them to beat the Reds," Blackadder said. "They are on a roll and anything can happen but we're not worrying about anything other than this week."
Crusaders 28 (Zac Guildford try; Dan Carter con, 6 pens, drop goal) bt Bulls 13 (Dewald Potgieter, Wynand Olivier tries; Morne Steyn pen). HT: 16-3
