TONY Miller is under no illusions about the importance of Sunday’s trip to Rochdale as the Dons close in on a top three finish.
Doncaster moved to within a point of second placed Workington Town with a 40-22 victory at home to London Skolars at the weekend.
Finishing in the top three would hand the Dons a huge advantage in the end-of-season play-offs - and dramatically improve their chances of reaching the Championship One Grand Final.
And it could be within Doncaster’s grasp if they can defeat Rochdale at Spotland on Sunday (3pm).
Miller said: “It’s our biggest game of the season - without question.
“We’re on the same points as Rochdale with a game in hand on them so a win would put us in a very good position.
“We know we’re in for a tough game.
“They play a very expansive game and it’s a wide pitch at Spotland.
“So we need to make sure we defend properly first and then use the ball well when we get it.
“There’s one point separating five teams at the moment, it’s a very tight league,” he added.
“We just need to make sure we keep on doing the things we have been doing in recent weeks to try and push for that top three.”
The Dons celebrated a fourth successive win on Sunday against a much-improved London side - although they were made to work hard for the victory.
Miller’s side weren’t at their best before the break but still took an 18-10 lead into half time.
The visitors then closed the gap to two points at the start of the second half when David Williams burst through a static defence.
But as the Skolars ran out of gas, Doncaster got better as the game wore on and tries from Dominic Dee, Nev Morrison, Chris Spurr and Carl Hughes wrapped up a fourth win on the bounce.
First half scores for the Dons came from Morrison, Jack Ely and Craig Robinson who brilliantly bulldozered his way over the line from five yards.
Miller said: “London are a good side and they will have a big say on who finishes where in the table.
“I’m glad we’ve got both of our games against them out of the way.
“They were better than us in the first half but we stuck together and in the second half we started going through them.
“And our completion was good which had a massive bearing on the game.
“We came on strong after half time and I fancy our chances against any team in the last twenty minutes.
“They’re a fit group of lads and we’ve got a lot of athletes in the side.”
Dons announced this week that powerful prop Dominic Dee, who was on loan from Featherstone Rovers, has signed for the club on a permanent deal.
Miller will check on the fitness of Mike Coady ahead of Sunday’s trip to Rochdale after the on-loan centre suffered a recurrence of a troublesome shoulder injury.
Craig Lawton is likely to miss out with rib and finger injuries but Stu Sanderson could be involved after an X-ray confirmed he had not broken his leg against London.
