Mulumbu missed Wednesday's 3-2 defeat at home to Manchester City as he served a one-match ban, although the Baggies are without central defender Jonas Olsson for the same reason after he collected his fifth yellow card in midweek.
On-loan winger Scott Sinclair is also available after recovering from a hamstring injury, as well as being ineligible for the game against parent club City, but goalkeeper Ben Foster (foot) and striker Nicolas Anelka (groin) remain out.
