Tuesday's crucial encounter broken down...
Millwall travel to Shrewsbury Town this Tuesday night (kick-off 7.45pm) for a Sky Bet League One encounter with meaning at both ends of the table.
Following Saturday's 3-1 victory at The Den over Scunthorpe United - a 14th game without defeat in SE16 - The Lions find themselves three points behind Southend United, who currently occupy the final Play-Off spot.
However, in what is increasingly becoming a condensed pack, Neil Harris' outfit are just six points off 3rd-placed Fleetwood Town, with a game in hand on Bradford City and Scunthorpe, the other two teams in those four coveted positions.
At the other end, Shrewsbury are fighting relegation to Sky Bet League Two and sit in 21st place, two points behind Gillingham - this weekend's opponents - and will be just as desperate to claim all three points at Greenhous Meadow.
The midweek meeting will be the 39th between the two, with Millwall currently having a stronghold on the fixture, winning 17 to The Shrews' 12.
However, The Lions will be hunting revenge after the last meeting saw the visitors win for the first time in south London for 54 years in December 2016.
Despite having 57% possession, 17 shots on goal and 13 corners, the home side could not find a way past a resolute defence, with Louis Dodds' well-worked 17th-minute strike proving fatal.
The Lions' last trip west was more fruitful, though, with Steve Morison and Lee Gregory (pen) on target as the club got off to the perfect start on the opening day of the 2015/16 campaign in the searing Shropshire heat.
Ben Thompson struck Millwall's 'Goal of the Season' in the return fixture at The Den in the April, with the partnership of Morison and Gregory on target once more in a 3-1 win.
More historically, The Lions have history of thumping wins over The Shrews.
The deadly duo of Teddy Sheringham and Tony Cascarino struck in October 1987 as Millwall won 4-1, whilst a year earlier, Michael Marks completed a hat-trick as The Lions downed The Shrews 4-0.
John Lyons also took home the matchball on the club's only FA Cup meeting, as Millwall were 5-1 victors in January 1980.
