Arsenal's Laurent Koscielny is to serve a three-match suspension after his appeal against his sending-off in Sunday's win over Everton was dismissed by the Football Association.

The 31-year-old received a straight red card for his reckless first-half challenge on Enner Valencia and will therefore miss Saturday's FA Cup final against Chelsea and the first two domestic fixtures of next season.

Arsenal beat Everton 3-1 despite his dismissal, but his confirmed absence is a further disappointment for manager Arsene Wenger, who also has fitness concerns over fellow defenders Gabriel Paulista and Shkodran Mustafi.

“Laurent Koscielny will serve a three-match suspension with immediate effect after a claim of wrongful dismissal was unsuccessful,” an FA statement read.
