Zlatko Krmpotic’s unbeaten run in all competition as Zesco United coach came to an end on Saturday when they were beaten away by Napsa Stars at National Heroes Stadium in Lusaka.
The Serb came into the match unbeaten in ten games since his appointment in February with seven wins and three draws in all competition.
However all that came to a screeching halt when Napsa nicked one for their own history books with a 1-0 victory over the league leaders.
That result saw Napsa end their winless run against Zesco dating back to 2012 when they returned to the FAZ Super Division for the first time since 2000.
Leaders Zesco’s loss also saw them suffer their first league loss in 2017.
Collins Sikombe’s 14th minute goal handed Napsa the win that saw them rise to 9 points and within one point of Zesco.
Lumwana Radiants could reclaim top spot on Sunday should they beat or draw at home with Konkola Blades.
Lumwana are tied on 10 points with zesco.
Meanwhile, newcomers Nakonde won their debut FAZ Super Division match on Saturday after downing 9-time champions 2-0 in Nakonde.
Danny Silavwe and ex-Nchanga Rangers striker Kabeya Mulume were on target in the 39th and 52nd minutes respectively.
Nakonde rise to 6 points and out of the bottom four while Wanderers stay last in 20th minute on zero points from 5 games played.
But Nakonde’s colleagues Buildcon suffered their first league defeat when Nkwazi beat them 1-0 thanks t a 16th minute Jeff Lungu goal.
The result ended Buildcon four match unbeaten start in a team that only has two Zambian players in their ranks.
Elsewhere, Nkana’s two-match revival was halted by Green Buffaloes who beat them 3-2.
Brian Mwila, Adrian Chama and Happy Kaunda were on target in the 45th, 85th and 93rd minutes respectively.
Nkana struck through Walter Bwalya 76th minute free kick and Ronald Kampamba in the 88th minute.
