Polokwane City defeated AmaZulu 1-0 in their Premier Soccer League match held at Princess Magogo Stadium on Tuesday.
In the 10th minute, Zwane had to make a change when Keegan Allan was injured and Bongani Zungu was brought on.
Zwane's charges went down after previously picking two back-to-back victories, and this means he has to go back to the drawing board and come up with a plan that will see Usuthu return to winning ways.
Bulelani Nikani scored for Rise and Shine in the 15th minute, a result that took them to the fifth position, while AmaZulu are sixth.
