Spireites boss Paul Cook is pleased with his side’s progress despite the 3-2 loss at the Keepmoat.
With Chesterfield sitting in an impressive fifth spot in the fledgling table following promotion last term, the manager said: “I think we’ve equipped ourselves really well at this level and you can see what the supporters think at the end of the game, clapping the team off, because they know that we’ve done our best.
“We have moved up a level and the level of finishing has also moved up. I felt sick for the supporters (at Doncaster) because we have let them down when they travelled across in numbers, but we had enough chances to get something from the game. Our supporters were a credit throughout.”
Cook added: “We’re an honest group and we have to defend better than that.
“We spoke to them after the game, we spoke for ten minutes about it at half-time and then we conceded straight after half-time.
“A manager can come out and make excuses, but we have to work hard on the training ground and be better than that.”
“Whether you were from Doncaster or from Chesterfield, you would have left the game saying ‘what a good game of football’. Both sides were very committed, and they have some fantastic players, but so have we.”
Spireites will be hoping to have Gary Roberts (hamstring), Daniel Jones (hamstring) and Georg Margreitter (concussion) available for the game at home to Notts County on Saturday but Sam Morsy, who also picked up a hamstring strain in the Rovers match, looks set to miss out.
Sam Hird and Drew Talbot remain on the long term absentee list.
County, 11 places but just four points behind Spireites, have drawn their last three League One games, two of them being goalless.
Shaun Derry has a squad that includes former Manchester United pair of Roy Carroll and Alan Smith.
