Brandon Thomas-Asante has been suspended for three matches following a breach of FA Rule E1.1 in Saturday’s FA Cup third-round tie at Chesterfield.
In the dying seconds of Saturday's FA Cup third-round match against Chesterfield, the 24-year-old clashed with Jeff King. The FA reviewed the incident which took place in the 92nd minute.
While King was being treated, Thomas-Asante scored to make it 3-3 and force a rematch.
He will miss the Championship games against Luton Town and Burnley, as well as the rematch against the Spireites on Tuesday.
Brandon Thomas-Asante has seven goals in all competitions this season for Albion.
The Baggies will not appeal the judgement of the Football Association.
Thomas-Asante has five goals in his previous eight Baggies games, bringing his season total to 12.
This includes five at the start of the season for Salford, from whom he was bought on deadline day in August by then-Baggies coach Steve Bruce.
