Arsene Wenger has been handed a touchline ban for Arsenal’s final Champions League group game against Steaua Bucharest on 12 December.
The ban imposed by Uefa comes after Wenger was sent to the stands after a row with the fourth match official during Arsenal’s 3-1 defeat at Sevilla on Tuesday.
The offence carries an automatic one-match suspension and will also deny Wenger access to the dressing room.
It is the first time in his career that Wenger has received a touchline ban but the Frenchman will have three days to appeal.
The incident occurred when Wenger was angered by apparent time-wasting by Sevilla’s Daniel Alves and remonstrated with Dutch official Reinold Wiedemeijer, who asked the Arsenal boss to leave the pitchside.
Wenger appeared reluctant to leave the area and watched the final minutes of the match from behind perimeter advertising boards, rather than in the stands.
