Muguna, who was signed by K'Ogalo from Western Stima this season, picked a knock during club's last match and has been ruled out of the clash against the 'Slum Boys'.
Muguna has confirmed the same on his official facebook page; "Good morning friends. A slight knock I picked during our last game has ruled me out of tomorrow's clash against Mathare United. I hope to be back in action next weekend. Thanks for your support. Let's turn up and cheer the boys on."
Muguna has also grabbed a goal since he joined the former champions and will be greatly missed on Sunday.
