Gloucester coach Dean Ryan saw his side lose their grip on the top spot in the Guinness Premiership at the weekend even though his team weren't playing.
Bath have leapfrogged their west country rivals after making up their extra game with a victory over London Irish. Both teams have the same number of points, but Bath have moved to the top on points difference.
Gloucester had to sit out last weekend's games because of the EDF Energy Cup semi-finals and Ryan will be keen to see his side get back to winning ways at Worcester this weekend having suffered four defeats in their last six Guinness Premiership matches.
The sell-out Heineken Cup quarter-final clash with Munster will be Gloucester's 13th game at Kingsholm this season in all tournaments. To date they have won 10, lost one - to Leicester Tigers - and drawn one.
Will it be lucky or unlucky 13 for the home side on Saturday, 5 April?
