KCB came from a goal down to draw 1-1 with Wazito FC in a pre-season friendly played on Friday.
The Bankers had won their opening game against AFC Leopards 2-0 with Wazito defeating Mathare United 4-1, meaning Friday's winner would have gone top of the group in the four-team tournament.
It was the Fred Ambani led side who took a deserved lead after just 22 minutes when Mathews Odongo rose highest to head in a corner from Burundian defender Karim Nizigiyimana.
KCB were reduced to 10 men when Nicodemus Onyango was sent off after a dangerous tackle on Wazito's Hassan Ali, but being a friendly game, the player was replaced.
Simon Abuko was brought down in the danger zone in the 77th minute, and veteran midfielder Dennis Odhiambo made it 1-1 from the penalty spot.
