Relegation is a serious threat for Quins, who went bottom of the Premiership just as they were starting a redevelopment of The Stoop.
Chief executive and head coach Mark Evans admits his team face a real dog-fight but he remains optimistic. He said: "There are six of us now who are covered by seven points - so there is a long way to go yet." Quins face Castres and Munster in the Heineken Cup in the next two weeks.
