The Blues stayed in touch with their win over the Kings last weekend, but the Lions are also in a desperate hunt for competition points.
Their conference rivals the Sharks have been the major beneficiaries of the Hurricanes' recent visit to South Africa. They saw Chris Boyd's men thrash the Lions 50-17 before they beat them 32-15 in Durban, and, now the Lions have had a week's rest to dwell on their slip, they are likely to come out roaring against the Blues.
"We had a bit of a buffer on the Sharks [in the African Two conference], but gave it up with that loss to the Hurricanes," coach Johann Ackermann told South African media.
"We are basically level [on the table with the Sharks]. There are just six games remaining - three now and another three after the June break.
"In the context that this is a home game and the Sharks are hot on our heels, that makes this a hugely important game.
"Neither of us [Lions and Sharks] can afford any more slips.
"We have really worked hard to fix the mistakes we made in the last match against the Hurricanes and especially a lot of detail was spent on the breakdown area which wasn't up to scratch in our last match," said Ackermann.
The Blues have proven remarkably good at the breakdown this season - using the ball has been their main problem - so the battle in the contact area is likely to be a defining one.
