West Bromwich Albion have been charged with misconduct by the Football Association over crowd disorder during their FA Cup derby defeat by Wolves.
January's fourth-round tie at The Hawthorns was halted for almost 40 minutes amid trouble in the stands.
The game, won 2-0 by Premier League side Wolves, was the first meeting between the Black Country neighbours in front of supporters since 2012.
Albion have until Wednesday, 20 March to respond to the charge.
"It's alleged that the club failed to ensure its spectators and/or supporters conduct themselves in an orderly fashion and don't behave in an improper, offensive, violent, threatening, abusive, indecent, insulting or provocative way," a statement from the FA said.
