Lincoln manager Steve Tilson was left disappointed after his side's good run of form came to a temporary halt in a 2-0 defeat to Chesterfield.
Craig Davies and Dean Holden netted as the Spireites overcame the Imps, who had previously lost just one of their last seven games.
"The final result was probably a bit harsh on us," said Tilson. "The first goal was just one of those things that don't normally happen. The second goal was a free header inside the box.
He added: "Apart from that we competed very well. We showed a lot of commitment and desire. We were always on our game and even when we were two goals down, we were pushing forward.
"The result was disappointing but the players gave everything. Trevor Carson will be disappointed with the way he conceded the first goal but it shows the character of the lad that for the rest of the game he had an almost faultless display. That's the sign of a good goalkeeper.
"He's a great lad and nothing fazes him. He made a mistake and just got on with it. He will be a top goalkeeper but for the moment I'm just pleased that he's here and doing a fantastic job for us."
Chesterfield manager John Sheridan was glad to get back to winning ways.
"I thought we were excellent," he said. "Lincoln made it a very tough game for us and were always going to be a big threat but I thought we dominated the game.
"The first goal gave us a high. It was unfortunate for their keeper but Craig Davies was right in there and kept calm. Craig is always hustling and bustling and if you do that the chances fall for you.
"Their keeper made a wonder save from Robertson but we got the second goal five minutes from the end and deserved to win. I was very pleased by the way we played. Six or seven of the players did well. I had some players missing and had to make changes so full credit to the lads who came in."
