Both Caley Thistle and Ross County have been hit with notices of complaint from the Scottish FA after their highly-charged Scottish Cup replay.
The Highland rivals are both alleged to have breached rule 204, where three or more players or members of staff from one team are involved in a confrontation with opposing players or staff.
Brad McKay and Michael Gardyne clashed at the end of extra-time during the replay at Caledonian Stadium on February 19, which sparked a melée between the two sets of players close to the touchline.
Referee John Beaton also carded eight players during the fifth round tie. The game was tied 2-2 at the time and Caley Thistle went on to triumph 5-4 on penalties.
Both sides have until March 14 to respond to the charges, with a principal hearing date of March 21.
