Top spot in the Varsity Cup will be on the line when defending champions Tuks host Pukke on Monday.
Tuks have 16 log points going into round five and Pukke 14. In Stellenbosch, Maties (10) will look to move past opponents Shimlas (11) into third place.
In the bottom half of the standings, there is just one log point between UJ and UCT ahead of their battle in Johannesburg, while Wits will be hoping to break their duck in the competition when they host NMMU.
Tuks remain the only unbeaten side following their bonus-point win over Ikeys on the Green Mile last week, but will face a serious test of their title credentials against a Pukke side full of confidence after their demolition of the Madibaz in Port Elizabeth.
Maties would have taken confidence from consecutive victories in the last two rounds after going down in their first two matches, but they will be confronted by a Shimlas team that showed UJ no mercy in Bloemfontein last week to storm up to third place.
UJ find themselves down in seventh place after that heavy defeat, but their play-off hopes are by no means over and they will be right back in the mix if they manage to overcome Ikeys on home turf. UCT have lost both of their home games this season, but are unbeaten on the road, and they will be hoping for another win away from home to move back into the top four.
The Madibaz are coming off two consecutive defeats at home, where they were previously unbeaten since 2012, so they will want to respond with a convincing performance against bottom-dwellers Wits who are desperate to end their 11-match losing streak in the competition. Wits fell just short of notching their first-ever Varsity Cup win against Maties in Stellenbosch last week, and will be aiming to go one better at home against a Madibaz side low on confidence.
In the Varsity Shield, defending champions CUT will be back on home soil after their bonus-point win against UWC in Bellville on Thursday, and they will face a TUT Vikings side hoping to bounce back from consecutive defeats.
The UKZN Impi remain in second place following their hard-fought draw with the Fort Hare Blues in Alice on Thursday, and they will have a chance to put some daylight between themselves and the third-placed Blues when they host bottom-placed UWC in Durban.
