Salvador: Portugal defender Pepe faces the possibility of a three-match ban for violent conduct after being sent off in the first half of Monday`s World Cup Group G game against Germany.
Pepe lent into Germany striker Thomas Mueller with his head, making contact and applying pressure in a needless altercation that could bring him a stiff punishment.
The Brazil-born center back had caught Mueller in the face in an innocuous-looking challenge but took umbrage as Mueller went down, returning to the forward and thrusting his forehead against the German`s.
Serbian referee Milorad Mazic had no hesitation in dismissing Pepe in the 37th minute.
A red card brings a mandatory one-game ban at the World Cup but that is usually extended in the case of a sending-off for violent play.
