Arsenal and Atletico Madrid have been charged by Uefa over incidents in Thursday’s Europa League semi-final.
Atletico coach Diego Simeone was sent to the stands following Sime Vrsaljko’s early red card in the 1-1 first-leg draw at Emirates Stadium.
Simeone was charged with insulting a match official and Atletico with improper conduct of the coach and the throwing of objects.
Arsenal were charged after fireworks were set off.
Both hearings will take place on 4 May, one day after the second leg in Madrid.
Marseille, who beat Red Bull Salzburg 2-0 in France in the first leg of the other semi-final, also received two Uefa charges, for setting off fireworks and the blocking of stairways.
