The Hammers went to arbitration at the FA after they dismissed their original appeal, but the FA have not changed their mind and the striker will now be suspended for three crucial games.
West Ham were furious that Carroll’s adjudged elbow on Chico Flores was worthy of a red card and a three game ban.
Flores has come under fire for his theatrics on the day and has taken to Twitter to hit back at Hammers fans and to plead his innocents.
Boss Sam Allardyce will now be without his key man for games against Aston Villa, Norwich and Southampton and so Carlton Cole or Marco Borriello will fill his void.
West Ham are still on the warpath with the FA though and they feel the decision could be a season defining one with the Hammers in serious relegation trouble.
