Leaders Nkana will battle to stay top of the FAZ Super Division when they visit struggling Napsa Stars on Sunday at Woodlands Stadium in Lusaka.
With second placed Zanaco slowly closing in on Nkana, who leads by two points, Kalampa must beat Napsa to remain top.
Nkana sits on 27 points from 12 points while Napsa are third from the bottom with 12 points.
Unlike Nkana who searching for their 9th win of the season, Napsa are looking for only their third victory.
Meanwhile, Forest Rangers host Zanaco at Trade Fair Grounds on Sunday in another delayed Week 14 match.
Zanaco hopes to continue breathing heavily on leaders Nkana as they tackle resurgent Forest in Ndola.
