The Baggies are nine points adrift of fellow strugglers Newcastle heading into the match at The Hawthorns and know that only a victory will do.
The Scotland international, along with fellow second-half substitute Hal Robson-Kanu, will be pushing for inclusion in the starting lineup this weekend.
Indeed, Allardyce has near enough a full group of players to choose from, with full-back Kieran Gibbs - not seen since January - their only fitness and suspension concern.
Matt Phillips is one of those who could make way from the XI should Snodgrass return, though the winger has been directly involved in five goals in his last four Premier League appearances against Newcastle - something Allardyce may well consider.
West Brom possible starting lineup: Johnstone; Furlong, Ajayi, Bartley, Townsend; Snodgrass, Maitland-Niles, Yokuslu, Gallagher, Pereira; Diagne
