Middlesbrough defender Daniel Ayala will serve a three-game ban after failing in an appeal against his red card in Sunday's FA Cup 3-0 win over Sheffield Wednesday.
Ayala was sent off for barging over Fernando Forestieri 30 yards from goal moments after Boro had gone 1-0 up.
The Spaniard, 26, claimed wrongful dismissal and said the punishment was excessive, but his appeal failed.
Ayala will now miss games with Watford, West Ham and Accrington Stanley.
