Millwall play their final Sky Bet Championship away game of the season at Middlesbrough on Saturday evening (LIVE on Sky Sports, kick-off 5.30pm).
Sitting just one place and two points outside the top six, Neil Harris' side head to the Riverside Stadium looking to keep in touch - or leapfrog themselves into - the Play-Off positions with just one game remaining.
With as many as seven teams still mathematically in with a shout of claiming fifth and sixth places in the League table - and also with Aston Villa hosting Derby County this weekend - twists and turns are guaranteed as the campaign reaches its climax.
Harris will be forced into one change to his squad as Tim Cahill begins a three-match ban following a violent conduct charge after last Friday's 3-0 defeat by Fulham. Names such as Conor McLaughlin, Shane Ferguson or Harry Toffolo could come into contention as a result.
The Riverside Stadium has been somewhat a happy hunting ground for The Lions in recent times, with three wins coming in their last five visits. Jed Wallace and George Saville were on target earlier this season as Millwall defeated Boro 2-1 to gain their 19th win in 52 over The Smoggies historically - Middlesbrough have won 22.
Around 1,100 supporters will make the trip north tomorrow and the club, in conjunction with Millwall Supporters' Club, have subsidised coach travel to ensure as many fans as possible can commit to the journey. There will no be ticket sales on the day.
The club have been advised by Middlesbrough that rucksacks and any large bags will not be allowed into the stadium. Supporters making arrangements to stay in the city on Saturday night are advised not to bring them to the match.
Furthermore, a serious road traffic collision on Thursday, one lane of two on the A66 dual carriageway leading up to the Riverside Stadium will be closed eastbound for the forseeable future. This is likely to lead to considerable congestion on the carriageway.
