"Mukaisi is a good striker who has helped us a lot in the games he has played. His return is a plus to us especially against a team like AFC Leopards. He will give us a different dimension on the pitch and hopefully he will score.
"Kennedy Agogo is still out. I cannot give the exact date of his return but I believe it will be soon."
AFC Leopards are yet to beat Posta Rangers in the last six league games. The two teams played to a one all draw in the first leg.
