Newcastle United captain Fabricio Coloccini was sent off during their draw with Pacos de Ferreira for trading blows with Rui Caetano.
The Daily Mail says ref Jorge Sousa was forced to give both players their marching orders after the incident even caused a melee on the far side of the pitch.
Striker Shola Ameobi equalised for the Magpies on the hour mark, cancelling out Caetano's early goal.
