All you need to know ahead of Tuesday night's match
Last six League results
At home, they are without a win four matches since December's victory over Blackpool at Huish Park.
Yeovil have picked up just one win - a 2-0 victory at Birmingham - in their last 10 Championship games.
Mark Beevers (calf) is expected to miss out once more, and Ollie will also be without Shane Lowry, who serves the third of a four-match suspension. Ed Upson looks set to watch from the sidelines as part of an agreement made between the two clubs in the deal which took the midfielder to The Den from Yeovil on transfer deadline day.
Lions boss Ian Holloway can call on keeper David Forde, who is in the squad after recovering from a thigh injury, and Danny Shittu, who sat out the defeat to Burnley with a groin complaint.
Yeovil boss Gary Johnson will hope that defender Liam Davis and on loan midfielder Joe Ralls are fit to return.

What the managers say
Gary Johnson: "It's a massive game for us. We have to make sure we perform and get some points off of teams in the bottom half of the table. We haven't won that many games but the ones we did win, we've had players coming up with individual bits of brilliance, and we need to show that more often. It's a Cup final, a 'six-pointer', and it's all to play for."
Ian Holloway: "We approach the game to win it. We have to build on what we did at the weekend because large parts of it was excellent. If we play as well as that, we would beat a lot of teams in this division. The players are clear about what I want now. I believe we can go on a run and that confidence will come, and we have three exciting games to do that."
Football League sponsors Sky Bet have placed Millwall at 15/8 to win at Huish Park, whilst Yeovil can be backed at 7/5.
Glovers forward Ishmael Miller and Lions loanee DJ Campbell are joint 11/2 favourites to open the scoring, but Martyn Woolford, Millwall's top scorer, is available at a tempting 12/1 to score the first goal of Tuesday night's game. Click here for these odds and more.
