They host lowly Yeovil tomorrow night and look set to close within a couple of points of Derby County in third place.
Leon Barnett scored the second as Ipswich Town became their latest victim on Saturday, but the defender is set to miss out tomorrow after coming off with a hamstring injury. Rob Kiernan should replace him in the starting lineup.
Visitors Yeovil are level with fellow strugglers Charlton Athletic and Barnsley in the bottom three but could climb out of the drop zone with an unlikely win as Millwall have a worse goal difference in 21st.
Possible starting lineups
Wigan: Al-Habsi; Boyce, Ramis, Kiernan, Perch; McClean, Gomez, McArthur, Tunnicliffe; Powell, Waghorn
Yeovil: Stech; Ayling, Webster, Duffy, McAllister; Lawrence, Edwards, Lanzoni, Ralls; Miller, Hayter
Sports Mole says: 3-0
