Zesco United and Zanaco hope to secure their passage to the next phase of their respective continental engagements on Sunday.
In the Caf Champions League, Zesco head to Guinea to face Horoya in Conakry armed with a 4-1 lead from the first leg played on March 12 in Ndola.
A draw will suffice for Zesco to see them through to the pre-group knockout round that kicks off in April.
However, Zesco will be without coach George Lwandamina who has stayed behind to prepare Zambia for Wednesday 2017 Africa Cup Group E qualifier at home against Congo-Brazzaville in Ndola.
His assistant Tenant Chembo will be in charge of the away match.
And in the Confederation Cup, Zanaco are home at Nkoloma Stadium in Lusaka where they host Harare City in a first round, return leg tie.
Mumamba Numba’s side enjoys a 2-1 first leg lead they picked up in Harare on March 12.
