West Brom's appeal against the red card shown to Jake Livermore in their game with Huddersfield has been rejected.
The 32-year-old was sent off for violent conduct after a high challenge on Huddersfield's Fraizer Campbell.
He will miss Tuesday's trip to Blackpool, Friday's home match against Nottingham Forest and the 4 December away game against Coventry City.
Livermore will be available again when they play Reading at The Hawthorns on 11 December.
