There was a further rage when the Blackburn goalkeeper Jason Brown escaped censure when he clearly handled outside his penalty area although Burnley were lucky to escape an Olsen shot cannoned down off the crossbar had clearly crossed the line before bouncing out.
Burnley commence competently enough as they launched their seven game fight for Premier League survival but that command was lost within 15 minutes when the visitors took control and Jason Roberts provided Rovers first major threat but was denied by a desperate Jensen lunge to save.
Olsen was marginally offside when he drove in from 18 years but his next threat brought the penalty for which Jensen also received a yellow card and Dunn despatched the only goal of an otherwise disappointing match.
Blackburn were more tenacious throughout, a fact summed up Roberts who revealed greater resolve in winning possession despite faced by a four man home defensive formation.
Burnley were more positive in the second half but rarely troubled Jason Brown the visiting goalkeeper and in the 67th minute Olsen's shot off the crossbar should have confirmed Blackburn's superiority beyond doubt.
Burnley huffed and puffed throughout but their approach play lacked style and there was no quality when they put play the balls in from the flanks.
