Anthony Laffor scored a dramatic late winner for Sundowns.
SuperSport bagged four at home to progress.
A late penalty sent Platinum Stars through.
Wits head into the CCC after being eliminated by Al Ahly.
Sundowns remain on track to retain their title.
However, triumph they did, and Pitso Mosimane and his technical team will now be looking with interest at the draw tomorrow as they wait and see who will stand between them and a chance to retain their trophy.
The Brazilians have reportedly been named in Pot 1 of the draw alongside Zamalek, Al Ahly and Etoile du Sahel, meaning that they will avoid a trip to Egypt in the group stages.
Meanwhile, Bidvest Wits – who dropped into the CAF Confederation Cup after their defeat to Ahly – will go into tomorrow's play-off round draw alongside SuperSport United and Platinum Stars.
Matsatsantsa and Dikwena knocked out Ah Ahly Shendi and Vipers SC respectively over the weekend, and now have just one tie standing between them and the group stages of the competition.
The CCL group stages will get underway in May, while the playoff stage of the CCC will be played in early and mid-April.
