Read our full guide to Saturday's game against The IronMillwall travel to Glanford Park on Saturday to take on Scunthorpe United in a game that is being dubbed the 'Prostate Cancer UK derby'.
That is because The Iron, just like Millwall did in 2013/14, have Prostate Cancer UK's logo on their first team shirts for the current campaign as they too look to help raise awareness of both the disease and the support available from the leading men's health charity in the UK.
On the pitch The Lions will be looking to bounce back after a disappointing week which saw the club lose three games inside seven days at The Den.
But Millwall boss Neil Harris, who has a selection headache in defence, is upbeat and confident that his side will get better as the season goes on - starting on Saturday.
Views from both camps
Neil Harris: "I said to the players that we had a great start at Shrewsbury, where we were terrific. We were professional, organised and in control.
"(Since then) we've had a real bad week. But one bad week doesn't make a season. It doesn't make us a bad team and it doesn't make it a bad football club.
"We will stick to our game plan and to our beliefs and we will help the players get better."
Look out for a full pre-match interview with Harris on Lions PlayerHD later today.
Meanwhile, Iron captain Stephen Dawson says he and his team-mates are eager to bounce back after their 3-0 defeat to Wigan Athletic on Wednesday night.
"I'm expecting a tough, physical game on Saturday against Millwall," he said.
"I don't worry about the opposition because we've just got to take care of ourselves.
"As a group we know it's not good enough, but we know that games come thick and fast, which gives us a chance to put things right quickly."

Harris has confirmed that Shane Ferguson will miss the game with a hamstring injury that saw him limp off in the latter stages of Tuesday's defeat to Barnsley.
That leaves the Lions boss with a dilemma at left-back. Mark Beevers has played there in recent weeks but skipper Tony Craig could also deputise in that position should Harris opt to play Beevers at centre-back or recall Byron Webster instead.
Jimmy Abdou came through his return from injury against The Tykes unscathed and is likely to start in central midfield once again.
Up front, Steve Morison and Lee Gregory will be hoping for a repeat of the last away match at Shrewsbury, in which they both got on the scoresheet. Fred Onyedinma will also be hoping to build on his midweek brace.
Joe Martin (ankle) remains sidelined.
Ex-Millwall striker Darius Henderson, who is now at Scunthorpe, was an unused substitute at the DW Stadium on Wednesday but will hope to play some part against his former side.
Elsewhere for The Iron, Jamie Ness is a doubt with a hip injury but goalkeeper Luke Daniels is available again after suspension.
Niall Canavan and Luke Williams are sidelined with injury.
Saturday's meeting will be the 20th to take place between the two sides.
Scunthorpe have enjoyed the better record to date, picking up nine wins compared to Millwall's six in the previous 19 fixtures.
In League action, however, there is nothing to separate the sides with five wins each plus two draws.
The Lions have won their last two matches against Saturday's hosts - 3-0 at The Den and 2-1 at Glanford Park - which both came during the 2010/11 campaign.
