BRASILIA, June 23 — Cameroon midfielder Alex Song has been banned for three matches after his sending off in their World Cup Group A defeat by Croatia, organisers FIFA said today.

The midfielder was dismissed for elbowing Croatia striker Mario Mandzukic in the back during the first half of their 4-0 defeat in Manaus on Thursday which meant they could no longer qualify for the knockout stages.

The Africans, who lost 1-0 to Mexico in their opener, face hosts Brazil in Brasilia tomorrow in their final Group A match. — Reuters
