Galatasaray’s Marcao was red carded after headbutting and punching his own team-mate on Monday.
The Brazilian defender was dismissed just after the hour mark of Gala’s 2-0 league win over Giresunspor after losing it with winger Muhammed Kerem Akturkoglu.
The centre-back seemed to take exception to something that Akturkoglu said, as well as the winger putting his finger to his lips in a ‘be quiet’ gesture.
He responded by running from his own half to headbutt and then throw punches at the winger, and had to be restrained by team-mates before he was shown a red card.
“It is not a common occurrence,” said Galatasaray manager Fatih Terim.
“We all have all kinds of arguments in the dressing room, on the field. This is the first time I have seen such a position with his own team-mate on the field.
“We don’t know what’s going on yet. Whatever it is, it’s not nice.
“This incident was not pleasant in any way, but the solution belongs to us. Don’t worry, we’ll figure it out somehow.”
