Milton Keynes Dons 1-0 Dover Athletic
Ben Reeves' strike ended non-league Dover's FA Cup run and earned MK Dons a place in the third round.
Reeves struck in the second half after a first period of few chances in which Jason Banton fired wide for the hosts.
But Reeves found the net from inside the box with a decent finish while Patrick Bamford went close soon after.
George Baldock saw one shot fly just wide and another saved while Dover's Sean Raggett also hit his own post as Bamford missed an open goal late on.
VIEW FROM THE DRESSING ROOM
MK Dons boss Karl Robinson told BBC Three Counties Radio:
"It wasn't convincing, let's not hide that fact, but we're through to the third round.
"Arguably we were by far the better team, but we looked like we lacked a little bit of confidence, a little bit of an edge, a little bit of fluency to our play.
"At the moment we are picking at bare bones. But the young players have dug deep today; I thought Samir Carruthers was outstanding. Today he's really shown me his coming of age."
Dover manager Chris Kinnear told BBC Radio Kent:
"I'm disappointed, I thought the last ten minutes we really had a go and the chances we had, I think we could have got something, the lads have gone home disappointed.
"They should be Championship or Premier League looking at this place. Our lads have got to go back to work Monday, they've just come back from Dubai so it's a little bit different.
"We came here to have a go, you have to defend but why sit back and wait for them to score, but maybe we were over confident."
