They would of course be reliant on Carlisle United claiming maximum points at Sheffield Wednesday in order to do so, but should the Owls failed to claim all three points at Hillsborough and United beat the Dons then promotion would be secured.
United have played at Stadium:MK just once before today when the two teams were drawn together in the League Cup after the Blades had passed Chesterfield in round one - following goals from Drew Broughton (12 minutes), Chris Lucketti (20), Nicky Law (55) and Jon-Paul McGovern (78) the game was tied at 2-2 and forced into extra-time where the Blades went onto in with a rare goal from Geoff Horsefild (105).
The Blades were given a scare in their last outing; beating Leyton Orient 3-1, but they fell behind to a Kevin Lisbie (12 minutes) goal against the break of play - though the visitors came to defend in the hope of coming away with at least a point they could have seen themselves with three goals before the break had they not misfired.
United got themselves back into the game when a scrappy goal in a scrappy game from Lee Williamson (42) leveled the two teams score. In the second half a fierce strike from captain Michael Doyle (54) put the Blades ahead. On the hour the O's were reduced to ten men when a dangerous Ryan Dickson tackle saw him red carded before Ched Evans (83) goal capped off a fine victory.
Blades boss Danny Wilson now has a selection headache ahead of tomorrow's game; Lescinel Jean-Francois (knee) and Chris Morgan (knee) are both absent through injury. Though he is without Erik Tonne (York City) who is away out on loan. Winger Michael O'Halloran, 21 could make his Sheffield United full debut after arriving on loan from Bolton Wanderers..
United are likely to field Stephen Quinn, 26 against his former club, the 'Ginger Messi' joined the Dons on loan from the Blades in September 2005, making his debut in a 3-2 defeat at Blackpool. He remained with the club until January were he returned to the Lane having made 14 (+5) appearances without finding the net.
Dons manager Karl Robinson will be searching for a home win as they look to accumulate their third successive victory in a row but know it won't be easy against Danny Wilson's Blades who currently have the best away form in the Division."Sheffield United are arguably one of the best teams in the league with some of the best players in the league, so it should be a great test for us and will show us how far we have come," said Robinson. "They beat us 2-1 at their place, but we had a man sent off and I thought that we exceptional in the second-half that day with 10 men."
"Danny (Wilson) has done an incredible job there and they now look favourites to go up automatically with Charlton, and rightly so because they have been playing very well lately. They can seal their promotion, so they will bring a lot of fans and make it a great occasion. But it is a big game for us too because we want to show what we are all about and will be focused on ourselves."
They recorded a 3-0 victory at Scunthorpe United last Saturday; their second 3-0 win in succession - Dean Bodwitch set the ball rolling after 11 minutes before Daniel Powll (54) doubled their lead. Former Blades striker Jordan Robertson (72) was dismissed for an off the ball incident and the win was wrapped up through Shaun Williams (85) late strike.
The double wins over Tranmere Rovers and Scunthorpe ended a run of four matches without a victory with just one point picked up in that dismal run. They are unable to obtain an automatic place this season but a point at least at home to the Blades this weekend would secure a play-off place with another shot at promotion looming.
Dons boss Karl Robinson is expected to be without defender Mathias Kouo-Doumbe (groin) through injury whilst midfielder Jay O'Shea (hamstring) is considered doubtful.
