National Super League leaders Ushuru FC suffered a shock 1-0 defeat to Kenya Police in a league match played on Friday.
The Taxmen fell by a solitary goal scored by Clinton Kinanga in the 68th minute to leave the top position wide open.
The Charles Omondi led side has 31 points from 19 games with Ushuru remaining on 41.
Wazito might go top with victory against St. Josephs; the latter will have to win by a bigger margin to go top though, but that will depend with the outcome of another league game between second placed Nairobi Stima, who will be hosting Eldoret Youth.
