Jamie Murphy, Steve Sidwell, Dale Stephens and Anthony Knockaert continue to patrol the middle of the park, while there is an unchanged back four in Bruno, Shane Duffy, Lewis Dunk and Sebastien Pocognoli.
For the visiting Royals, manager Jaap Stam makes three changes to the side that lost to another of their promotion rivals, Huddersfield Town, on Tuesday.
There is one change in defence, as Paul McShane replaces Jordan Obita alongside Chris Gunter, Tyler Blackett and Liam Moore, while George Evans is preferred to Liam Kelly as partner for Jordon Mutch and Danny Williams in the middle of the park.
Elsewhere, Joey van den Berg is named among the substitutes after missing the trip to Huddersfield with a hamstring problem.
