Robbie Fowler is on a three-month pay as you play contract
Martin Olsson's 10th minute goal sent Blackburn into the fourth round of the Carling Cup at the expense of fellow Premier League outfit Everton.
Blackburn handed a debut to striker Robbie Fowler and his neat one-two set up defender Olsson who rifled the ball past Everton keeper Tim Howard.
James Vaughan thought he had equalised but his header was ruled out for a foul on substitute keeper Jason Brown.
Substitute Tim Cahill had a late chance to level but sent his header wide.
Both teams made a host of changes for the game, with Everton resting Cahill, Mikel Arteta, Yakubu and Leighton Baines and Blackburn making seven changes to the side which defeated Fulham at the weekend.
The home side made the brighter start and took the lead through Olsson, who linked up well with Fowler to open the scoring.
Blackburn were forced to make their first substitution of the night soon after keeper Paul Robinson was forced off with a calf injury to be replaced by Brown.
Matt Derbyshire came close to increasing Blackburn's lead soon after and Howard was also forced into a good save from Keith Treacy.
