Warriors can still progress
Worcester kept their European hopes alive with an emphatic nine-try 57-13 victory over Bucharest Wolves at Sixways.
Marcel Garvey scored twice in the first half as the Warriors outclassed the Romanians, who played half the game with 14 men following four yellow cards.

Christian Loamanu then pounced with two quick-fire tries, with Wilkinson converting both to ensure a 22-3 half-time lead.
