Given the latest summer transfer window activity - some predicted he may hand out some debuts against Derby, with the likes of Samuel Iling-Junior, Charlie Taylor and Alfie Gilchrist all in line for debuts.
However, Mason has shown loyalty to the players who delivered the win at Stoke, naming an unchanged side with captain Jed Wallace keeping his place on the right flank.
It is likely though that the new trio could make debuts from the bench - with all three being named on the substitutes bench.
Elsewhere, there is no place in the squad for Karlan Grant and Krystian Bielik who are still out with injuries - having missed the victory at Stoke a fortnight ago.
Albion: Griffiths, Campbell, Mepham, Phillips, Styles, Mowatt, Molumby, Wallace, Price, Johnston, Heggebo
Subs: Wildsmith, Wallis, Bostock, Gilchrist, Taylor, Collyer, Iling-Junior, Diakite, Maja
