The Baggies will be hoping to maintain their position at the top of the table with a win, but the London outfit have lost just twice at home in the league this season.
However, their strong upsurge in form since the change of manager has tapered off somewhat, with just one win in their last five across all competitions.
The Lions now find themselves ninth, five points adrift of sixth-placed Bristol City with a game in hand.
As a result, Slaven Bilic's side will be keen to exact revenge but face a difficult task against a Millwall side that rarely lose at home.
West Brom do boast the best away form in the league, however, winning eight and losing just two of their 15 games on the road so far this term.
Additionally, the Baggies are the highest scorers in the Championship, netting a whopping 53 goals in just 30 games, and are the only side to have hit more than 50 so far.
Only a win can guarantee West Brom top spot at the end of the weekend, with title challengers Leeds United just one point behind in second place.
Millwall Championship form: WWDWLD
Millwall form (all competitions): WDWLLD
West Bromwich Albion Championship form: LDDLLW
West Bromwich Albion form (all competitions): WDLWLW
Millwall manager Rowett only has a few injury concerns to deal with ahead of the visit of West Brom on Sunday.
Ryan Leonard, however, may be in contention but is still doubtful and may not be risked.
West Brom boss Bilic has a similarly short injury list ahead of the Baggies' visit to London.
Millwall starting lineup:
Bialkowski; Romeo, Hutchinson, Cooper, M. Wallace; J. Wallace, Williams, Woods, Ferguson; Smith, Bradshaw
West Bromwich Albion possible starting lineup:
Johnstone; O'Shea, Ajayi, Bartley, Townsend; Sawyers, Livermore; Phillips, Krovinovic, Robinson; Austin
We say: Millwall 0-1 West Bromwich Albion
The Den is a difficult place to visit, but West Brom have the best away record in the league and the Championship leaders may just edge their way to an important win.
