Atletico Madrid boss Diego Simeone faces the prospect of sitting in the stands for his side's Europa League final clash should they overcome Arsenal.
The 47-year-old was dismissed in the early stages of Atleti's 1-1 draw with the Gunners on Thursday night after being left frustrated by a couple of refereeing decisions.
French official Clement Turpin ordered Simeone to watch the remaining 75 minutes of the match away from the touchline, and he has since been charged by UEFA with improper conduct and insulting a match official.
Simeone faces a possible four-game ban when the disciplinary panel judge the case on May 4 - a day after the semi-final second leg, meaning that the punishment will carry over into next season.
Meanwhile, Atletico have also been charged for objects being thrown by supporters during the match.
