Chesterfield manager Paul Cook told BBC Radio Sheffield:
"If you don't start a game you don't win it and we gave ourselves a mountain to climb - after eight minutes you're 2-0 down.
"I'm certainly not going to blame the players, we've had an up and down season and it seems to continue.
"Where we're at today and where we want to be are two different places. Unfortunately tonight we hold our hands up, it's not good enough."
