Paul Clement has made three changes from the midweek match against QPR, with Tyler Blackett, John Swift and Marc McNulty all in the starting line-up.
McNulty makes his first start on the road as a Royal, with Yakou Méïté likely to play on the wing as a result.
The back four remains unchanged, with the addition of Blackett likely to make it a five-man Reading defence on Saturday afternoon.
Swift and Leandro Bacuna start in midfield, alongside Saeid Ezatolahi.
Academy graduates Liam Kelly, Andy Rinomhota and Tom Holmes are all among the substitutes - with Holmes hoping to make his second senior appearance for the club.
West Bromwich Albion: Johnstone, Gibbs, Bartley, Livermore, Mears, Barnes, Gayle, Barry (c), Rodriguez, Dawson, Hegazi.
