Newcastle United will appeal the red cards shown to Jonjo Shelvey and Paul Dummett.
The pair were sent off in Friday night's 2-1 defeat to Nottingham Forest at the City Ground.
United manager Rafa Benitez also has a simple message for his players ahead of Saturday's home game against Birmingham City.
The two clubs were drawn against each other at St Andrew's in the third round of the FA Cup last night.
Meanwhile, Ian Cathro has outlined his footballing vision after leaving Newcastle, where he was on Benitez's coaching team, to become head coach at Heart of Midlothian.
