It was on a rare break on 75 minutes that the trouble erupted after a rash challenge deep in his own half by Anthony on Marc Sontag. The two players got into a scuffle on the floor and Anthony lost his cool, striking out at the Abbey player.
That prompted Sontag's brother Lee to race across the pitch and land a haymaker on Anthony and a melee ensued.
Referee Lloyd Wood sorted it out, first sending off Anthony and then Lee Sontag, who raced after the Tilbury youngster and followed him into the dressing room, where an altercation broke out, Anthony emerging covered in blood and clearly dazed.
Further ugly scenes followed as players and club officials from boths side got involved.
Mr Wood sent both teams to the dressing room and, after consulting with the FA, announced the match had been abandoned.
