BRAZILIAN star Rivaldo faces disciplinary action today for his over-reaction in an incident in last night's match with Turkey which saw Blackburn Rovers defender Hakan Unsal sent off.

Rivaldo collapsed clutching his face after Unsal kicked the ball at him, while the Brazilian was waiting to take a corner, though he was clearly struck on the leg.

FIFA communications director Keith Cooper said a disciplinary commission was sitting today to rule on the incident.

Cooper said: "We have gone into the World Cup making it clear there will be a clampdown on simulation, which is FIFA-speak for cheating. If the disciplinary commission think there is sufficient cause they will take a second or third look at any incident and rule accordingly."

Rivaldo is likely to face a fine rather than a suspension.

Cooper confirmed the commission will not discuss rescinding Unsal's red card, saying: "That's not open to question, solely Rivaldo's reaction."

The Turkish full-back became the 100th player dismissed at World Cups since the first tournament in 1930 but not the 100th red card - they were only introduced in 1970.

The disciplinary commission are expected to announce the suspensions that Unsal and Aston Villa centre-back Alpay will serve for their dismissals in the 2-1 defeat by Brazil.
