Zesco United toppled Zanaco from top spot on Wednesday following a 1-0 home win over Kabwe Warriors at Levy Mwanawasa Stadium in Ndola.
2016 runners-up Zesco’s win sees them swap places with the defending champions and go two points clear with six games left before the 2017 title is decided.
Striker Lazarus Kambole scored the game’s lone goal in the 33rd minute after receiving a clever pass from Simon Silwimba.
The goal was Kambole’s fourth from his last three games and takes his 2017 tally to 8 goals.
But Warriors were unfortunate to leave Ndola without a point after Jonathan Manongo saw his 79th minute shot come off the post.
Zesco have 62 points, Zanaco have 60 points while Green Buffaloes and Nkana are 3rd and 4th on 57 and 55 points respectively.
Meanwhile, Zesco’s victory came at a price after they lost through injury midfielder Kondwani Mtonga in the 24th and their top scorer on 15 goals Jesse Were in the 65th minute ahead of Sunday’s away date against difficult Nkwazi.
