Championship Millwall are through to the FA Cup quarter-finals after beating League One strugglers AFC Wimbledon 1-0.
The Lions came close to adding to the 1-0 advantage given to them by Wallace's early goal on a number of occasions in the second half but failed to beat Dons goalkeeper Aaron Ramsdale for a second time.
Millwall join Watford and Brighton in Monday night's quarter-final draw.

Good morning and welcome to The Independent's live coverage of today's FA Cup action.
We have three games for you this afternoon with Brighton and Derby kicking things off with Wimbledon, Millwall, Newport County and Premier League champions Manchester City all in action.
We'll have all of it for you right here so get your feet up, open up a browser tab and settle in for nine hours of the greatest cup competition in the world.
Team News
Could we see the first mini-shock of the FA Cup fifth round in today's early fixture? Frank Lampard's Derby - challenging for promotion in the Championship - have already knocked Premier League Southampton out of the competition. And it wouldn't be hugely surprising if they were to do the same to Brighton.
Chris Hughton's side are on a poor run of form in the league and will be wary of underestimating today's visitors. The winner will take their place in the last eight of the FA Cup.
Changes
Brighton have made eight changes to the team that fell to a 3-1 defeat against Burnley last weekend. Top scorer Glenn Murray is not even in the squad.
Derby make three changes: David Nugent, Tom Huddlestone and Craig Bryson come in. Ashley Cole, meanwhile, is on the bench.
Frank Lampard might feel he has an advantage in the FA Cup. As a player, he won it four times with Chelsea. That experience could serve his side well as they attempt to reach the latter stages of the competition. With several of the top Premier Clubs already knocked out, this is a real opportunity for Derby.
Chris Hughton has been speaking to the media ahead of kick off:
Some of the bigger sides have gone out, but for us it's always about taking it one round at a time. It's a great opportunity for somebody - we're part of that group of teams.
We're the favourites this weekend and we understand that. We'd always rather be playing at home against a side outside the top flight - but they're in really good form at the moment.
The teams are out at the Amex. Kick off is just a couple of minutes away now!
Brighton 0-0 Derby
2 minutes
Veteran right back Bruno links up nicely with Knockaert on the right and the hosts win the first corner of the game. It's played short and the ball that eventually comes into the box evades everyone.
Brighton 0-0 Derby
6 minutes
Derby have enjoyed plenty of possession in the early stages, although they've done little with it. They've settled well, though, and look untroubled at the back so far.
Brighton 0-0 Derby
7 minutes
Bissouma drives forward from midfield and makes his way into the box. He goes down under a challenge but the referee ignores his appeals for a penalty.
Brighton 0-0 Derby
12 minutes
Locadia goes down under a challenge from Malone on the edge of the box, but the referee appears to ignore the challenge. Derby's defender then picks the ball up, clearly assuming that he had been penalised, and a free kick is awarded.
Knockaert takes the set piece and draws the first save of the game from Roos, who tips the curling shot over.
Brighton 0-0 Derby
16 minutes
Brighton are putting the visitors under some pressure for the first time, penning them back in their own half. Jahanbakhsh puts a dangerous cross in from the right, which is headed out to Stephens on the edge of the box. His shot is blocked easily, though, and Derby clear.
Brighton 0-0 Derby
18 minutes
Derby have their first shot of the game, but it's not Nugent's finest effort. A long ball is played up to Waghorn, who knocks it back to the former Leicester striker. He drags his long range shot well wide of the far post.

23 minutes
Bissouma goes for goal from the free kick, hitting it low beneath the wall. He doesn't catch it well, though, and Roos stretches to his left to make the save.
Brighton 0-0 Derby
26 minutes
Huddlestone is robbed of the ball in midfield and Brighton break through Knockaert. The ball finds its way to Bissouma, who has time and space, but he slices a shot over the bar. It's another poor effort in a game of little quality so far.
Brighton 0-0 Derby
29 minutes
Knockaert, cutting in from the right, curls a shot towards the far post and brings a save from Roos, who parries the ball away. Brighton are in control of the game, but they haven't troubled Derby enough in the final third.
