Despite securing a 2-1 win at Hull City on Sunday which lifted them out of the bottom three, Blackburn remain deep in trouble and face an Everton side who have lost only once in 11 Premier League outings.

It is a crucial game for Allardyce's team and the Blackburn manager is hoping referee Alan Wiley picks up on Cahill after claiming Everton's Australia international "plays the man before the ball".
He added: "Tim Cahill uses his body and it's not often he concedes a free-kick, but most of the time we see him playing the man before the ball.
"Every player commits fouls. It's whether the referee sees it and sometimes they don't if a player is as clever as he is.
"It's certainly very difficult to spot from their point of view and the spectators' point of view. But you pick up on it if you have been in the game as long as we have.
"I'm not saying he's a dirty player, he just uses his assets very well."
Jason Brown is set for only his third League start since joining Blackburn in June 2006 as Rovers' first-choice goalkeeper Paul Robinson is struggling with a shoulder injury.
Brown believes an extended run in the first team could ignite his career after playing second fiddle to Brad Friedel, now at Aston Villa, and Robinson during his time at Ewood Park.
"It crosses your mind that you might have to get away to get first-team football," Brown said. "I am as ambitious as the next guy and I don't want my career to be about 'if only'.
"It has been difficult. After the opportunities I had earlier this season against Manchester United and Newcastle I thought maybe I had done enough to deserve a longer run. But the manager at the time decided that wasn't the case.
"That was fine and I just had to get on with it.
"This chance has come along and I will do the best I can and maybe get an extended run in the team."
