Albion's Sky Bet Championship trip to Plymouth Argyle will no longer take place on Saturday, January 27 (ko 3pm).
Both Plymouth and the Baggies advanced through to the fourth round of the Emirates FA Cup, meaning the two clubs will be in cup action that weekend rather than league action.
A new date and kick-off time for the clash at Home Park will be arranged in due course. Supporters will be notified at the earliest possible opportunity.
