The two sides are bottom of the table with the hosts (eight points) a point behind the visitors (nine), who in turn trail the Titans in fourth by four points. With the winner likely to retain some outside hope of staying alive, the loser will see their hopes all but ended, although the mathematics do state otherwise.
Knights coach Allan Donald says: 'I always have hope. We're sort of in a dark place right now, but we know where we stand. It's going to be tough, but we just have to concentrate on every single game now.' The Knights, who have just two wins from six games this season, were beaten by 55-runs in their last outing against the Titans on Friday night. Reeza Hendricks is back from South Africa 'A' duty to bolster their batting.
He is set to take the place of Diego Rosier, while Dillon Du Preez could return from injury for Corne Dry. The Dolphins too have had a torrid time so far in the competition. Thumped by the Cape Cobras on Friday, they will be without Imran Tahir and David Miller for the trip to the northern Cape.
But Khaya Zondo and Andile Phehlukwayo are back to bolster them. Donald says: 'We're all scrapping at the bottom there. They're a dangerous side and we all know that teams in that position can find a free spirit to play with. So both sides will be looking for that extra edge and we can't take them for granted.'
