And having lost their last Pool 1 tie at home to Sale Sharks, Dean Ryan's men really need a win when the tournament gets back underway. But their hopes of getting back on track were hit hard with the news that one of their most impressive performers could be ruled out until the New Year.
Argentine hooker Agustin Creevy suffered a knee injury in Friday night's Aviva Premiership defeat to Bath and has since had surgery. The 28-year-old had an operation to repair a meniscus tear and he now faces a lengthy spell on the sidelines.
No date has yet been set for his return but Ryan and co will be hoping it is sooner rather than later given his impact since arriving from Montpellier via the Rugby Championship last month. Creevy made his debut off the bench in the European defeat to Sale and has won regular praise from Ryan ever since.
"Gus has been ruled out after he was forced off through injury during last Friday's match," said Ryan, whose side are currently without a win in all competitions so far this season, having lost all seven Aviva Premiership fixtures and drawn one and lost one of their Amlin Challenge Cup games.
"It's obviously disappointing that he will not be available to us as he has had a fantastic start to his Warriors career."
A two-month absence would definitely rule Creevy out of the Amlin Challenge Cup games against Biarritz and would leave him facing a race against time to be fit for the two final group games against Sale and Oyonnax on the weekends of January 9-12 and 16-19.
He will also be unavailable for the entirety of his country's autumn tour of Europe, starting with Saturday's trip to Twickenham to face England.
