The 1st XV had the misfortune of running into a Coventry side, riding high at the top of National One and in fine form, and slumped to a comprehensive 48-13 defeat.
The Extra 1st XV lost as well for only the third time this season. Mark Garratt's side went down 38-26, but gained a four-try bonus point and must now beat Ampthill to secure second place in Zoo Shield One.
There was much better news on a super Sunday for the club. The Under-18s moved into the last 16 of the National Cup with an excellent and hard fought 24-12 away win against a strong Ealing Trailfinders side.
OEs had taken a narrow 14-12 lead at half-time courtesy of an early try from centre Zac Filmer and a length of the field interception from Dillon Robertson, both converted by Brendon Paulsen.
No.8 Ed Thompson added a third score shortly after the restart and Cameron Hancock rounded off an outstanding performance by OEs with a fourth try shortly before the end.
In the only game at College Meadow last weekend, OEs Women moved to within a point of clinching the league title in their first ever season of competitive rugby when they edged past Sutton & Epsom 22-15 in a thrilling top-of-the-table showdown.
Tries from Becky Goodwin, Helen Harris, Miriam Taylor and Clare Chiu clinched a nail-biting victory for the unbeaten league leaders. They now entertain Cuffley Ladies in the final game of the season at College Meadow next Sunday, requiring just a point to finish top of London & SE One.
