Equity Bank caused one of the major upsets in the FKF Shield Cup this season when they beat champions Bandari 1-0 to reach the semi-finals on Wednesday.
The Bankers who reached the last eight following a 1-0 win against Vegpro, needed a 57th-minute goal courtesy of Sande Katumba to knock out the defending champions and proceed to the semi-finals where they will now meet the winner between Tusker and AFC Leopards.
It was Bandari who came into the game as favourites and having beaten Sigalagala 5-0 in the Round of 16, they were already tipped to get past the Bankers, who are handled by former Harambee Stars striker John Baraza.
