Posh have to overhaul Derby County, Barnsley and Reading to get out of the Championship drop zone, but the latter beat fading Blackburn Rovers 1-0 to move move 10 points clear of Grant McCann’s men.

Posh have a game in hand which is at play-off chasing Queens Park Rangers tomorrow (12.30pm) when a win would move them off the bottom at least.

Posh are two points behind Derby with two games in hand after the Rams failed to turn domination into a victory over Coventry City at Pride Park. Indeed they needed a very soft penalty to earn 1-1 draw, Barnsley were beaten 2-0 at Sheffield United to stay five points clear of Posh, but five points from safety.
