The Spireites bowed out of the Isuzu FA Trophy at the fourth round stage after a 2-0 defeat away to National League South side Welling United.
Chesterfield made 11 changes as they fielded a young side consisting of players from the academy.
The early exchanges didn’t bring much in the way of chances with Luke Chadwick claiming a couple of early crosses.
Welling’s Antony Papadopoulos and Chiori Johnson had the first shots of the games; both of which went wide of the goal. The latter was soon forced off with an injury, being replaced by Jack Burchell.
Enoch Muwonge, who was promoted to the starting XI just before the first whistle, almost opened the scoring from close-range but found Jack Brassey in the way.
Chadwick was the busier of the two goalkeepers as he did really well to parry away Lachlan Byrd’s stab towards goal.
Just before the break, the Spireites found their first chance of the game. Ben Rossiter stole the ball from a Welling defender but snatched at his effort and the ball rolled wide of the mark.
The Blues made a change at the break as defender Charlie Wragg was replaced by Harvey Thomas.
The hosts opened the scoring in the 51st minute. David Kamara controlled a cross into the box before firing his effort beyond Chadwick and into the roof of the net.
Welling came close to adding a second when TJ Bramble was picked out with a good portion of the goal to aim at, but Koby Errat-Thompson threw himself in the way of the effort before clearing the ball.
The lead was doubled with seven minutes to go; Muwonge got away from Ryley D’Sena before lashing the ball into the back of the net.
Liam Jessop almost pulled a goal back in added time as his effort from the edge of the box was parried away by Riece Charles-Cook.
