Middlesbrough defender Daniel Ayala will serve a three-match ban after failing in a bid to have his red card against Sheffield Wednesday overturned.
The 26-year-old Spaniard will be suspended after having wrongful dismissal and excessive punishment claims rejected by an independent regulatory commission.
A statement on the Football Association's website read: "Daniel Ayala will serve a three-match suspension with immediate effect after his wrongful dismissal and excessive punishment claims were unsuccessful, following an independent regulatory commission hearing.
"The Middlesbrough defender was sent off for serious foul play during the FA Cup game against Sheffield Wednesday on Sunday (8 January 2017)".
