Arsenal have appealed against the red card shown to defender Thomas Vermaelen in Saturday's match against West Ham, it was announced on Monday.
Vermaelen was sent-off shortly before half-time for bringing down the Hammers' Guillermo Franco inside the penalty area. A statement from the Football Association on Arsenal's website said: "The FA has received a claim for wrongful dismissal from Arsenal defender Thomas Vermaelen. A regulatory commission heard the claim yesterday."
