Chesterfield suffered a 2-1 defeat to Rotherham United at the Proact Stadium on Wednesday afternoon.
The Spireites fielded a number of first-team players for the reserve game against the Millers - who also named a strong side.
Tendayi Darikwa got some vital minutes under his belt as he continues his recovery from an operation on a double hernia. Danny Whitaker and Mark Randall also started the game alongside loanees Jordan Clark and Alex Henshall.
Both sides adopted an attack-minded approach from the start. First Kieran Agard had his strong run at goal halted by Jamie McNicholas and Tim Whittaker before Kristian Ramsey-Dickson lashed a powerful effort of the bar from a tight angle.
The Millers thought they should have had a penalty after 10 minutes when Jonathan Wafula slid in on Daniel Kearns, but the referee waved away the protests and awarded a corner.
The opening 25 saw little in the way of clear-cut chances. Kayode Odejayi had two opportunities with his head but failed to trouble Josh Barrington.
On the half-hour mark Rotherham took the lead though the lively Kieran Agard. Jonathan Wafula allowed a long ball forward to bounce over his shoulder and Agard pounced to break the deadlock.
Chesterfield responded well though and were close to levelling the scores just moments after Agard's opener. Danny Whitaker found some space down the left, cut inside and fed Jordan Clark on the edge of the area who saw his powerful effort strike the crossbar from 20 yards.
The game began to open up towards the latter stages of the first half and Agard almost raced clear of the defence from another long ball, but Tim Whittaker denied the striker with a well-timed, last-ditch challenge. Neither side could capitalise on half-chances and the opening 45 minutes ended with the visitors ahead.
Rotherham started the second half brightly and took the lead through a brilliant indivdual effort from Danny Kearns. The left winger drove into the box, lifted the ball over a defender before rifling an effort into the top corner.
Again Chesterfield responded well and almost reduced the deficit back to one. Ramsey-Dickson latched onto a through ball, rounded the keeper but had his effort blocked on the line.
It didn't take long for the striker to find the net though. Morgan failed to clear a cross back in from the corner and Ramsey-Dickson headed the ball into the net from 8 yards, a well directed header by the striker who had to generate all of the power himself to steer it past Shearer.
The striker was beginning to cause real problems for the Rotherham defence. Tendayi Darikwa fizzed a low cross into the box and Ramsey-Dickson got across his man to steer it at goal, however Scott Shearer got down smartly to save.
Chesterfield should have been level with 20 minutes remaining. Jordan Clark picked out Danny Whitaker in the area with a lovely pass, but the midfielder dragged his shot harmlessly wide from 12 yards.
Mark Randall was next to test the Rotherham goalkeeper with a driven effort from 25 yards but it was straight at Shearer who gathered comfortably.
The Millers though they had restored their two-goal advantage after Nicky Walker rolled the ball into the bottom corner, but he was adjudged to have handled the ball in the build up and the goal was disallowed.
At the other end the impressive Ramsey-Dickson went close to levelling the scores. Mark Randall picked out the striker in the box with a trademark pass, but the striker's header fell just wide of the post.
Tim Whittaker had a glorious chance to snatch a point at the death. The defender got clear of his marker from a corner but couldn't get a good enough connection to head past Shearer.
The visitors would have extended their lead further but for an expertly-timed challenge from Jack Broadhead and the game ended 2-1 to Rotherham United.
