Albion are trying to halt a run of six defeats in their last seven league matches.
Wigan manager Roberto Martinez will restore his first-choice players after resting a handful for the drawn FA Cup fourth-round match against Bolton at the weekend.
Hugo Rodallega and Charles N'Zogbia should both be back in the Wigan starting XI, while goalkeeper Ali Al Habsi will come back despite Mike Pollitt's clean sheet.
Callum McManaman and Victor Moses impressed against the Trotters but James McCarthy and Franco Di Santo's first-team return should keep them out. Antolin Alcaraz remains out with a soft tissue problem.
