Isinde and Zirintusa are among the 16 players that the Ndola based side has released.
The duo who joined Buildcon last year, failed to live up to the expectations of coach Arena Gulgleimo. Gulgleimo believes that the remaining players and the new ones will improve the team that finished ninth in the league last season.
"We have been training and we have done some work, and we are soon going into camp. We have new players and we know we will be playing against more experienced teams, but that is not an excuse, We have to learn quickly,"Gulgleimo said.
