Nkana sent a statement about their survival hopes on Saturday following a 2-1 home win over Prison Leopards at Nkana Stadium in Kitwe.
The victory handed third from bottom Nkana its second successive league victory from three home games in May that boosted their survival hopes with six games left to avoid demotion.
Zimbabwe defender Gilroy Chimwemwe scored and provided an assist on the day as Nkana also avenged their 2-0 first leg away loss to Prison on December 30.
Chimwemwe put Nkana ahead with a rather speculative shot from range in the 28th minute that Prison goalkeeper Charles Kalumba let in by his very own high standards.
