In comparison to the quality that they produced against West Bromwich Albion three days earlier, Preston fell well short during the first half versus Bristol City at the weekend.
North End ultimately fought back for the second time to salvage a point courtesy of a last-gasp equaliser, but Ryan Lowe will regard the 2-2 draw as points dropped in their bid to challenge for the playoffs.
Preston have now accumulated 12 points from his seven league games, a strong return all things considered, but only claiming a share of the spoils at Deepdale has left them eight points adrift of the top six.
With 18 games remaining, there is still time to move into close proximity of the teams above them, although they need to take advantage of fixtures such as the one on Tuesday.
As a result of his double against Bristol City, forward Emil Riis Jakobsen has now scored 12 in the Championship this campaign, four of them coming in as many appearances.
Millwall’s season has petered out over recent games, the East Londoners suffering three defeats in a row to Bristol City, Nottingham Forest and Blackpool.
