The Scottish Football Association will investigate the tunnel flare-up after Hamilton's 2-1 win over Hearts on Sunday, where three post-match red cards were issued following two shown to Hearts players during the game.
"The Scottish FA will conduct a full investigation into events that occurred in the aftermath of the Premier League game between Hamilton Academical and Heart of Midlothian," the SFA said in a statement.
Visitors Hearts finished the Scottish Premier League game with nine men after captain Michael Stewart and defender Ismael Bouzid were sent off - Stewart then comically landing on his bottom after kicking out in anger while walking down the tunnel.
There was no laughing after the game, however, when players and club officials clashed in the tunnel, with red cards for two more Hearts players, Ian Black and Suso Santana, as well as Hamilton's Leon Knight.
The match had begun with a minute's silence as a mark of respect for a teenaged Hamilton supporter who died suddenly during the week.
