Kaoru Mitoma starts for Albion as they aim to clinch Europa League top spot.
The Japan winger returns to the XI as the Seagulls face Marseille at the Amex.
Albion have named three centre-backs in their side.
Lewis Dunk, Jan Paul van Hecke and Igor are all in a team with no specialist full-backs.
That could indicate a back three with wing-backs although Pascal Gross and Jack Hinshelwood, both of who can play a version of full-back, are in the side.
Albion: Steele; Van Hecke, Dunk, Igor; Gross, Hinshelwood, Gilmour, Buonanotte; Adingra, Joao Pedro, Mitoma. Subs: Verbruggen, McGill, Kavanagh, Milner, Dahoud, Lallana, Baleba, Veltman, Hinchy, Ferguson, Chouchane, Duffus
Marseille: Lopez; Meite, Mbemba, Balerdi, Lodi; Clauss, Ounahi, Veretout; Harit; Aubameyang, Vitinha. Subs: Ngapandouentnbu, Blanco, Gigot, Kondogbia, Sarr, Mughe, Ndiaye, Nadir, Soglo, Murillo.
