United were back to winning ways with a 1-0 away win over Chippa United last Sunday courtesy of Mxolisi Machupu.
For the second successive clash, Stars needed Eleazar Rodgers to prevent a defeat on their name at home to Polokwane City in midweek.
SuperSport will be looking to get back amongst the top five with a win after being leapfrogged by Polokwane City’s 2-0 win over Golden Arrows on Saturday.
Stars are out of the bottom-two for now, but cannot rest on their laurels and will likewise search for a win to easing their relegation fears.
Matsatsantsa will miss the services of Aubrey Modiba due to a one-match suspension, with Stars boasting a clean bill of health.
The first round battle went 1-0 in favour of United, with the suspended Modiba getting the winner in Bethlehem.
