The Spiders showed their resolve last week with a wonderful 2-1 win at Stenhousemuir but must follow that up against The Blue Brazil or it will be rendered meaningless.
Queen's will also be looking at results away from Hampden tommorow with Methil and Elgin the venues that they hope East Fife and Stenhousemuir defeat Arbroath and Elgin respectively.
Queen's could be without a fit right back tomorrow with Alan Trouten, Ross Clark and Paul Paton all doubtful. Also out are Richard Bowers, Kjartan Finnbogason and Stuart Kettlewell
Allez les Hoops.
