Newcastle United have lodged an appeal over Fabricio Coloccini's Wear-Tyne derby dismissal.
Coloccini was sent off in yesterday's 3-0 defeat to Sunderland at the Stadium of Light.
The game was goalless when Coloccini challenged Steven Fletcher in the box.
Referee Robert Madley awarded a penalty, converted by Adam Armstrong, and showed a red card to Coloccini, who will miss Saturday's home game against Stoke City if the appeal is unsuccessful.
A club statement read: Newcastle United have lodged an appeal with the Football Association for the wrongful dismissal of Fabricio Coloccini during Sunday’s Tyne-Wear derby match against Sunderland at the Stadium of Light.
"Coloccini was given a straight red card by referee Robert Madley in first half injury time following an incident involving Steven Fletcher, which resulted in the awarding of a penalty kick.
"The appeal will be heard by a Regulatory Commission tomorrow afternoon and the club will be notified of the result shortly afterwards.
"Should the dismissal stand, United’s captain will miss Saturday’s Premier League fixture with Stoke City at St. James’s Park."
