Retford lost ground on the rest of the pack at the top of the NCEL Premier, after a disastrous 12-minute spell on Saturday.
Badgers hosted Staveley Miners Welfare, and went down 4-1, despite dominating the first half.
A morning inspection passed the pitch fit for the game to go ahead, and Retford boss Richard Sennett welcomed back Andy Walkden and Richard Medcalf to the starting 11.
There was a place on the bench for new signing Paddy Mullen.
Reece Thompson went close early on as his shot was turned away for a corner by Tom Turner in the Staveley net.
Andy Walkden met the resulting set-piece, and struck the foot of the post.
Kyle Hadley showed vision to float the ball into the run of Thompson who was unlucky as a defender managed to cut out the ball.
More pressure from the homes side saw Jake Stannard’s effort crashed against the legs of a defender and away to safety.
Staveley had their best chance of the first half when Matt Thorpe broke free but could only put the ball behind.
The deadlock was broken in the 19th minute when Richard Medcalf played a good ball to Thompson who got past the last man to stroke home.
The chances kept coming for Retford and this would prove to be costly later in the game, Medcalf firing wide of the post.
Staveley had a golden chance to level through Oli Ryan who crashed his header against the crossbar.
But they were level on 31 minutes when a corner ball was sent into the box and Ryan put his header past Barford.
Retford should have been ahead minutes before the break when Walkden rose to win a header from a corner that was saved by the feet of the keeper and off the line.
The second half started with Hadley finding Medcalf who did well to turn and fire in a low cross that was only just collected by Turner.
Neither side were able to create much in the early stages of the second period.
For Retford, Thompson put a chance wide, Jack Cross wentclose from a ball from Ben Muirhead, and Craig Fisher found the keeper with the follow up.
On 76 minutes Staveley took the lead, as a cross in from the right found Thorpe who appeared to be climbing on Fisher, and met the ball with his head to put his side into the lead.
Two minutes later he lead was extended as Walkden lost the ball on halfway setting Staveley on a break and Michael Trench slotted home.
The game was over in the 88th minute when Trench struck his second, Staveley’s fourth to seal the win.
Retford were lucky not to lose Thompson in stoppage time as he angrily reacted to a challenge, shoving a Staveley player in front of the referee, but a yellow card was the punishment.
United will look to shake off the defeat on Saturday as they face a trip to Barton Town.
