British Lionhearts suffered a 5-0 defeat in their penultimate World Series of Boxing group match against German Eagles in Hannover.
Welshman Sean McGoldrick was outpointed 2008 Olympic bronze medallist Veaceslav Gojan, while Joe Cordina lost a unanimous decision to Artur Bril.
Kaupo Arro, Lawrence Osueke and Uaine Fa also came up short for what was an under-strength Lionhearts squad.
British Lionhearts have already qualified for the quarter-finals.
McGoldrick suffered with the pace set by the experienced Gojan who took all five rounds before Cordina suffered similar problems against Bril.
Stefan Hartel's slick counter-punching saw him outbox Estonian Arro before WSB debutant Osueke lost a closely contested bout with Xhek Paskali.
The Lionhearts' miserable night finished with Fa losing a points decision Emir Ahmatovic, despite leading after three rounds.
Their final group match will see them square off with Ukraine Otamans on 1 March in Bethnal Green's York Hall.
