Tony Miller says the Dons have had a timely wake-up call ahead of a potential play-off campaign.
Miller refused to be too downhearted about last week’s 24-10 defeat to Dewsbury, insisting the disappointment of their unbeaten run being brought to an end had happened at the right time.
“It was the kick up the backside I think we needed,” the head coach said.
“It’s come at the right time as well.
“We know we’ve got to be at our best to make sure we make the play-offs and definitely when we’re in there.
Miller spoke to the Times prior to last night’s rearranged clash with York City Knight for whom a defeat would have sealed relegation.
And he felt the Dons remained in a strong position.
He said: “The defeat was disappointing because the run came to end but we’re still in a very good position.
“Sixth spot is still in reach for us and that was the case beforehand so it’s not too bad.
“It will give us plenty of things to work on to make sure we’re ready for Sheffield on Sunday.”
A sixth placed finish would see the Dons up against the seventh placed side in the first stage of the play-offs while finishing eighth would see them play fifth placed Batley.
Sunday’s home game with Sheffield Eagles will be Millers’ last regular league game in charge of the Dons.
And he has called upon former players and supporters to attend.
He said: “It’d be great to get plenty of old faces down there on Sunday to give me a send off – people I’ve played and coached with.
“It’d also be good to see a few old supporters down as well.
“The one thing I’ve been disappointed with over the last couple of years has been the crowds.
“We’ve got a fantastic core support but we deserve to be getting a few more down, particularly with how well we’ve done over the last couple of seasons. We never lost at home last season, it can’t get much better than that.
“I’m not sure what the reasons are but what I do know is people don’t know what they’re missing.
“I hope a few more come out on Sunday.”
A Doncaster spokesperson said: “Both Sheffield and ourselves have worked hard over the last few years to put rugby league on the map in South Yorkshire, and have done so with great success.”
