All you need to know about Sunday's game
Millwall have secured their place in the Sky Bet League One Play-Offs - and now aim to deny Gillingham a top six spot when the teams lock horns in a mouthwatering League One fixture at the Priestfield Stadium on Sunday (12.30pm).
The Lions booked their place in the League One Play-Offs last weekend thanks to a comfortable 3-0 home win against Oldham Athletic - a sixth straight success on home soil.
However The Gills, in the top six all season until just two weeks ago, face a make-or-break date with The Lions. Justin Edinburgh's side are involved in a three-way tussle with Barnsley and Scunthorpe United for sixth spot. Barnsley are currently in the driving seat - just - on 71 points and with a +2 goal difference ahead of seventh-placed Scunthorpe.
Gillingham are two points behind on 69, but know that a victory against Millwall, coupled with defeats for Barnsley and Scunthorpe would see the Kent side sneak back in and claim sixth spot.
With Barnsley facing a trip to table-topping Wigan, themselves needing three points to clinch the title, and Scunny at Sheffield United, The Lions could potentially have a major say in determining who takes that final sixth spot.
What the managers say
Neil Harris: "We're not thinking too much about where we are finishing in the table, whether we play at home or away first, I'm quite relaxed with that. Our home form has been outstanding since Christmas and our away form has been top drawer all season.
"What I am focused on is beating Gillingham this Sunday. It's a huge game for us and one that I am desperate to win.
"We were disappointed with the first 15 minutes of the game when we played them back in December when we were behind and had a red card too. It made it very difficult to get back in to the match, but even so our 10 men showed real spirit and determination.
"This is a big one for us and our fans. We will go there with real purpose to win the game."
Justin Edinburgh: "I believe we deserve to be in those Play-Offs. We still have that glimmer of hope and I believe we will win our game, and when that happens and the final whistle goes we will still be reliant on two other teams. That is going to be difficult, but the players here have got a duty to do and I'm sure they will do it.
"Our job is quite clear - there is no other result we need other than a win. We know what we need to do, there is no grey area for us, nothing less than a win will be enough for us to get where we want to be."
Millwall have midfielder Shaun Williams available again after the completion of his three-match suspension.
Top scorer Lee Gregory could also be back in the frame having missed the last couple of games against Bury and Oldham Athletic following surgery on a stomach muscle injury.
Shaun Cummings (knee) remains a long-term absentee.
Elsewhere Gills defender Aaron Morris faces a late fitness test as Justin Edinburgh's side look to sneak into the Sky Bet League One Play-Offs.
Morris suffered a knee injury in last week's defeat at Burton but a scan has revealed it is not a major problem.
Lions fans travelling to Priestfield are advised to arrive in plenty of time to help ensure that there are no delays entering the stadium.
The beamback at The Den is completely sold out. There will be no ticket sales on the day.
The Gills and Lions have met 95 times, and Millwall's win-ratio is nearly twice that of our Kent rivals with 47 victories from those previous encounters.
Gillingham have tasted victory on 27 occasions - most recently at The Den in December 2015 - with the remaining 21 games finishing all-square.
However when it comes to games at the Priestfield Stadium, The Lions' will be determined to improve on a recent run that has reaped one win from the last 11 visits. Seven of those have ended in defeat and the other three games finishing all square.
Millwall's last success in Kent came back in November 1997 when goals from Michael Black, Paul Shaw and Paul Wilkinson secured a 3-1 win in a game that also saw Gills' Brian Statham sent off with the score at 1-1.
have placed Gillingham as 21/20 favourites for Sunday's game, while Millwall are 5/2 outsiders. The draw can be backed at 5/2.
Gills' duo Bradley Dack and Rory Donnelly are 5/1 favourites to open the scoring with Millwall's Steve Morison coming in at 11/2 to grab the first goal of the game, whilst Aiden O'Brien (13/2) and Jamie Philpot (8/1) are also priced as first goalscorer.
Morison, who has 18 goals this season, is 50/1 to record his first-ever hat-trick for The Lions and Byron Webster, who bagged a brace against Oldham last weekend, is 100/1 to repeat that feat on Sunday.
