Bolton defender Gary Cahill has lost his appeal over his red card at Arsenal on Saturday.
The 24-year-old challenged his dismissal by referee Stuart Attwell for a 64th-minute challenge from behind on striker Marouane Chamakh, and his case was heard by a regulatory commission on Tuesday.
An FA statement said: "At a regulatory commission hearing, a claim for wrongful dismissal from Bolton Wanderers defender Gary Cahill was dismissed.
"As a result, Cahill's three-match suspension will remain and will be served with immediate effect."
Cahill and boss Owen Coyle can at least console themselves with the fact that the commission did not view their appeal as frivolous, a finding which would have seen the player's ban extended to four games.
