Chesterfield didn’t lose any ground on sixth place after both Bradford City and Doncaster Rovers lost on Tuesday night.
Bradford, who currently occupy the last play-off spot, lost 2-1 at Swindon Town, who closed the gap on second-placed MK Dons to two points, but have a game in hand.
Doncaster in seventh on the same number as points (45), meanwhile, went down 3-1 at home to Bristol City and have played the same number of games as the Spireites.
Sheffield United continued their recent resurgence with a 2-1 win over Rochdale at Spotland. Marc McNulty and John Brayford with the Blades’ goals that sees them consolidate fifth spot.
Preston North End kept pace in fourth with a 1-0 win over mid-table Walsall and Scunthorpe United dropped to 17th after Josh Scowen scored the only goal of the game for Barnsley.
League One clubs Coventry City and Peterborough United offered the football community a reminder of the pressure for success by parting ways with their respective managers this week.
Steven Pressley leaves his post with the Sky Blues after watching his side lose a two-goal lead against the ten men of Sheffield United to draw 2-2 in his 100th game in charge of the club.
The result saw Coventry fall in to the bottom four ahead of Saturday’s game against MK Dons and had a lasting impression on the club’s hierachy who moved swiftly to end Pressley’s time.
Chief executive Steve Waggott said: “This has been a very difficult decision from a personal and professional point of view, and we would like to place on record our thanks to Steven for his efforts over the last two years.”
Waggott pointed to results which has seen six wins in their last 28 games under Pressley and without a victory in their last seven. Neil MacFarlane and Dave Hockaday have been placed in temporary charge.
It came hot on the heels of another management casualty, which saw Darren Ferguson and Peterborough end an eight-year association with one another after a 3-0 defeat to MK Dons last Saturday.
Ferguson, son of former Manchester United manager Sir Alex, has seen his side win just one of their last five and currently sits in 15th place - four points off the play-off picture.
The 43-year-old had been back with Posh for a second spell since 2011 but left the club on Saturday evening along with coaches Gary Breen, Gavin Strachan, Jimmy Walker, Stewart England and Marc Lindsey.
A statement by chairman Darragh MacAnthony read: “It saddens me to say that the club has this evening parted ways with one of the finest managers in our club’s history.
“After speaking with Darren, he feels that a new challenge is needed for both himself and the football club.” Academy manager Dave Robertson has been put in temporary charge.
