Mitrovic received a straight red card for his actions, but the FA previously said that the standard three-match ban was “clearly insufficient” on this occasion.
The Serbia international’s dismissal came at the conclusion of a chaotic couple of minutes late in the second half, in which Willian was sent off for conceding a penalty for handling Jadon Sancho’s effort on the goalline before Fulham manager Marco Silva was also shown a red card for remonstrating with officials.
Fulham, who were leading 1-0 at the time thanks to a Mitrovic goal, went on to lose 3-1 at Old Trafford.
