Millwall welcome Oxford United to The Den this Saturday (kick-off 3pm) for their final League game on home soil this season.
Following the Easter period - a weekend which saw The Lions register one win and one defeat - Neil Harris' side currently occupy the final Play-Off spot, one point ahead of Southend United, their nearest challengers.
Oxford, meanwhile, are now out of the race for a top six place, but will want to finish their first season back in the third tier strongly, after a campaign that has seen a second successive Wembley Stadium appearance in the Checkatrade Trophy Final.
Victory for The Lions coupled with a defeat for The Shrimpers at Shrewsbury Town will see a spot in the end-of-season lottery all but confirmed - any other outcome will see the race go down to the final day.
Saturday's meeting will be the 53rd between the two sides, with Millwall on top historically, winning 23 matches to Oxford's 17.
Last October, Aiden O'Brien bagged the winner in a 2-1 win at The Kassam Stadium after Steve Morison thumped home a 'Goal of the Season' contender to cancel out Liam Sercombe's opening goal.
That was the first League meeting since February 2001, but there were three Cup ties in between - most notably in last season's Johnstone's Paint Trophy, where, despite Lee Gregory's goal winning the Southern Area Final Second Leg for Millwall, a 2-0 defeat at The Den saw The Lions miss out on a Wembley appearance in the Final.
Harris notched one of many hat-tricks in a Lions shirt in September 2000, as his treble, coupled with loanee Sam Parkin's double, saw The Lions down The U's 5-0 on their way to winning the Division Two title.
Ex-Lions striker Paul Moody owns the distinction of scoring for both sides. Along with now assistant manager David Livermore, Moody's strike condemned relegated Oxford to a 2-0 defeat at The Manor Ground in February 2001, but the tables were turned in January 1996, as the iconic target man was successful in a ding-dong 3-3 draw. That particular game saw Alex Rae (2) and Chris Malkin on the score-sheet for Millwall, with Bobby Ford and Stuart Massey netting along with Moody for the visitors.
A number of presentations will be taking place pre-match at The Den on Saturday, including the awarding of the MSC Player of the Year trophy to Steve Morison, from 2.40pm onwards, so be sure to take your seats early.
All food and drink kiosks will be open throughout the stadium.
