Albion Under-18s couldn't retain their early lead, as they fell to a narrow defeat against Fulham's youngsters.
Leading talisman Reyes Cleary had broken the deadlock after just six minutes, but Oliver Sanderson's penalty levelled the game going in at the break.
After a tightly-contested second 45, momentum swung in the Cotatgers' favour when centre-back Leon Machisa was dismissed for the young Baggies with just over 10 minutes to go.
And two minutes later, Peter Gilbert's side's man disadvantage proved costly as Harvey Araujo struck with nine minutes remaining to ensure the points remained in the capital.
Albion: Hudd; Williams, Machina, Phillips, Humphries; Whitwell, Oliver (Mfuamba 45+1), Wangusi (Okoka 45+1); Heard (Higgins 74), Love, Cleary.
