Neil Harris has warned his Millwall players that they must be wary of Blackburn Rovers' "firepower" in tonight's Championship match at Ewood Park.

Millwall will feel tonight's game is a must-win affair given that they are four points from safety with just three games of the season to play.

Harris will be hoping that their need for the points will be too much for Blackburn, but Rovers come into the match after scoring three against Nottingham Forest on Saturday.

"It's a huge game for the club with the situation we're in," Harris told the club website.

"We know it is going to be an extremely difficult test. They've got some really good players and an exciting style of play.

"The goals they have got in the team are huge. They have got an expensive squad with some real firepower."

Millwall's hopes of escaping the drop could be given a boost if the side directly above them in the table, Rotherham United, are docked three points for fielding an ineligible player.
