MK Dons progressed into Round Two of the Emirates FA Cup after overcoming Eastleigh 4-3 on penalties.
MK Dons were in full control for the Emirates FA Cup clash, but an impressive performance from Eastleigh's Joe McDonnell denied Russell Martin's side a goal.
The Dons were unable to find a way past the resolute home defence with the tie heading to penalties.
Scott Fraser scored the decisive penalty as Russell Martin's side progressed in the Cup.
Russell Martin made five changes from the side that drew with Northampton Town on Tuesday night.
Lee Nicholls was back between the sticks, meanwhile, Baily Cargill, Lasse Sorensen, Stephen Walker and Louis Thompson were all handed a start at the Silverlake Stadium.
Elsewhere, Dean Lewington, Regan Poole, Baily Cargill and David Kasumu retained their place. - Daniel Harvie and Warren O’Hora also remained in the starting XI.
Eastleigh were on the front foot from the first whistle and could’ve taken the lead had Ben House converted Michael Green’s cross.
The first MK Dons chance of the game fell the way of Louis Thompson. Sorensen’s initial corner was cleared back out to the Dane. Having shaped to cross, Sorensen picked out Thompson on the edge of the box who saw his effort hit the side netting.
Eastleigh had penalty appeals turned away after House went down inside the area, Cargill was then on hand to deflect Miley’s effort from six-yards out.
Morris was the next Dons player to test McDonnell, he cut onto the right foot after some good play from Harvie. His curling strike was saved by the Eastleigh shot stopper.
With 25-minutes gone, the lively Ben House saw his acrobatic header land on the roof of the net from Green’s cross.
Eastleigh came within inches of taking the lead moments before the half-time whistle as Jack Payne’s effort ended just wide of the post.
The hosts were presented with the first chance of the second-half, they won possession in the middle of the park before House was found unmarked. The Eastleigh striker rushed his chance and dragged wide of the far post.
Morris came closest to opening the deadlock on 55-minutes after his header from Harvie’s corner cannoned off the post. The Dons recycled possession before Morris’ strike from the edge of the box was blocked.
Thompson then almost netted a contender for Goal of the Season. After a smart one-two with Morris, Thompson advanced into the area. Having beat two men, the Midfielder then chipped an effort towards goal – McDonnell was on hand to tip over the bar.
From the resulting corner, Walker twisted and turned before finding Harvie. He shifted onto his left, but once again McDonnell saved.
Gladwin looked to make an impact off the bench, he found a yard of space on the edge of the area, but his effort was into the side netting.
It was once again Gladwin trying his luck, he once again had time on the edge of the box, but was unable to keep his effort down.
Morris was the next to go close, after some good work from Walker. The Middlesbrough loanee won possession on the halfway line before driving MK Dons forward. He played in Morris who saw his effort end over the bar.
Walker produced a chance that was all his own doing, Sorensen found his run down the right before the forward made his way into the area. Having faked a shot once, the striker saw his goal bound effort blocked at the last second.
At the other end, Wynter was presented with the chance to give Eastleigh the lead, he found himself unmarked in the area, but was unable to test Nicholls with his header.
It was Walker who had the first chance in Extra Time, he lost his marker after Lewington’s pass, but his powerful effort was saved by McDonnell. Seconds later, it was the young striker who saw his curling effort go narrowly wide.
Gladwin’s deliveries on the right were causing Eastleigh all sorts of problems, his latest was inches away from Morris.
Lewington’s low effort forced McDonnell into another save, he got down to his left well to deny the MK Dons captain.
McDonnell continued to be the thorn in the side of the Dons attackers, he produced the best save of the clash with just three-minutes remaining. After Bird flicked into the path of Walker, the loanee shifted onto his left foot before pulling the trigger. Somehow, McDonnell got a hand to the shot to tip over the bar.
