Gor Mahia tasted the second defeat in less than a week this season as they were thrashed 5-1 by RS Berkane in Morocco on Sunday.
Kogalo has been a difficult nut to crack for oppositions but they were punished on a day they were far from their best.
RS Berkane dominated the game from start to finish with Mohammed Aziz, El Helali, As Saidy, Dayo and Kodjo Laba scoring for the home side.
While powerhouse Lawrence Juma got the consolation goal for Kogalo the wound had already been inflicted.
Despite all the hype around reaching the semifinals, Gor's match preparation was a low-key affair.
This was Kogalo's joint-heaviest away defeat in CAF Champions league in one season following their 4-1 loss to El Zamalek earlier.
The loss means Kogalo are knocked out of the competition with a 7-1 aggregate losing 0-2 at home in the first leg and 5-1 away.
The humiliating defeat completed a miserable week for Kogalo, and are now left with the Kenya Premier League to fight for this season after crashing out of the Sportpesa shield on penalties against Bandari.
Coach Hassan Oktay may feel disappointed after overseeing Kogalo go through to the quarters and will have the board to blame after not backing his team when it all mattered.
