Dunstan Nyaudo will have to make a late decision on whether to risk playing striker Masita Masuta and Cliff Kasuti in the tie.
Cliff Kasuti limped off on Friday’s training while Masita picked an injury against Bandari in the last league match, rendering them serious doubts for the home game against the league defending champions.
Nyaudo will have to make a late decision on the two ahead of the only KPL match on Saturday.
Gor Mahia are at the summit with 40 points after 16 games while Ulinzi are seven places and 10 points behind the league leaders.
Gor Mahia also boasts of a better head to head record having won eight of their last 16 meetings four matches ending in a draw and losing four.
K’Ogalo have scored six goals and conceding just two in the last six meetings with their host with a one-nil scoreline, save for the 2015 season-first leg clash where Gor Mahia won 2-0.
Even the draws between the two ‘Armies’ have always ended in stalemate apart from the 2017 first-leg encounter where the game registered a two-all scores.
