An in-depth look ahead to Saturday's match
Ian Holloway's Millwall side will look to sign off for the international break on a high with a win against in-form Derby County at the iPro Stadium on Saturday (3pm).
The Lions head into the game on the back of a winless September but can take confidence from the fact that they upset the odds with a 1-0 win on their last visit to face The Rams back in March.
Tuesday night's 3-1 home defeat to Birmingham stretched Millwall's winless run to five matches, whilst Steve McClaren's Derby, who sit fourth, are unbeaten in seven League games and have yet to lose at home in 2014/15.
Striker Lee Gregory will hope to retain his place in the starting line-up after scoring his first Lions goal on Tuesday.
His strike partner against Birmingham, Mathias Ranegie, picked up a hamstring injury on the night and will miss Saturday's game.
Nicky Bailey (calf) and Lee Martin (knee) remain sidelined, as does long-term absentee Carlos Edwards.
Aiden O'Brien, who impressed after coming off the bench for his League debut earlier this week, looks set to travel with the squad.
Saturday's fixture will be the 51st meeting between Derby and Millwall - and there is nothing to split the clubs going into the game with 19 wins apiece in all competitions.
In League action, though, it is Millwall who hold the superiority with 17 wins to 13 for Derby, though The Rams do have the better head-to-head record in Cup competitions.
The most recent encounter was at the iPro Stadium back in March when Steve Morison's second-half header secured a 1-0 win for The Lions.
