Blackburn's strikers drew yet another blank in a 2-0 loss at Dundee United.
Rovers missed a host of chances in a goalless stalemate against Hibernian in midweek and again failed to fire as their Scottish Premier League hosts ran out comfortable winners thanks to strikes in each half from Andis Shala and Prince Buaben.
Rovers manager Sam Allardyce freely admits his side could be short of goals in the coming Premier League campaign but of more immediate concern will be the fitness of Chris Samba, Paul Gallagher and Ryan Nelsen, who all picked up knocks.
