Albion were beaten 2-0 by Norwich City in a Sky Bet Championship match on Saturday afternoon.
Goals either side of half-time from Josh Sargent and Jonathan Rowe were the difference at Carrow Road.
Carlos Corberán’s men now have an eight-day gap until next weekend’s Emirates FA Cup clash against Wolves.
The boss made one change to his XI, bringing in Jed Wallace for Tom Fellows (illness).
Despite an encouraging start, Albion found themselves behind on the 13-minute mark - Sargent racing through and squeezing a finish past Alex Palmer, who did get a hand to it.
The goal seemed to spring the hosts into action, and they threatened again midway through the half, Palmer doing well to twice keep curling Jonathan Rowe efforts out.
Garbiel Sara found the roof of the net with a free-kick as the break closed in - and there was also time for the Baggies to have a goal disallowed, Brandon Thomas-Asante adjudged to have handballed before converting a close-range shot.
Corberán brought on Andi Weimann at the interval, and his team went close to equalising early in the second period when John Swift struck inches wide, while Wallace volleyed a difficult opportunity wide as well.
The visitors continued to push for an equaliser, but that left them open to the counter-attack - and Norwich took advantage with a lethal break 20 minutes from the end. City broke forward in numbers and Rowe was there to tap home.
Still, Albion created chances - Darnell Furlong seeing a header saved, substitute Daryl Dike firing over and, later, Weimann hitting off-target. They couldn’t find a way back, though, and David Wagner’s side came away victorious.
Albion: Palmer; Furlong (Pipa 83), Kipre, Bartley (Taylor 83), Townsend; Yokuslu (Chalobah 36), Mowatt; Wallace, Swift, Reach (Weimann 46); Thomas-Asante (Dike).
Substitutes: Griffiths, Pieters, Whitwell, Malcolm.
