They wrote: “Jarrad Branthwaite remains sidelined for a second successive game due to concussion protocols, while Jack Grealish is unavailable for selection due to a breach of Club discipline.”No official explanation of the breach has been revealed.

I think it was probably one of the easiest decisions he’s had to make [if he missed training].”Everton vs Newcastle: Live on talkSPORT Grealish won’t be playing, but Everton face Newcastle this evening hoping to reach the Carabao Cup quarter-finals.
