Strathmore Leos and Masinde Muliro University (MMUST) officially relegated from the division one competition at the Driftwood Sevens after losing their Challenge Trophy quarterfinal fixtures at the Mombasa Sports Club on Sunday 26 August.
The Leos fell to a 10-0 defeat to Kenya Harlequin as Northern Suburbs edged MMUST 7-5.
Also relegated are Kisumu and Makueni - the Kabeberi division two champions who also lost their semis games.
Hosts Mombasa defeated Kisumu 17-10 in their Challenge Trophy quarterfinal. Impala Saracens completed the Challenge Trophy semifinal pairings with a 29-7 win over Makueni.
Kisumu are however certain of division one rugby in the next leg - Dala sevens that they will host. They gave the prerogative to invite the other three relegated sides to their event.
MMUST had been relegated at the Kabeberi Sevens the weekend before and were top seeds for the division two at Driftwood.
But they got elevated to division one at the end of the coastal circuit - alongside Northern Suburbs - following withdrawal of Mean Machine and Blak Blad of Kenyatta University following an unfortunate accident in Friday night.
