Neymar is losing his battle to be fit for Brazil's first knock-out game in the World Cup - and fears are growing that his tournament may be over.
The Paris Saint-Germain forward will miss the clash with Cameroon this Thursday night and reports from South America suggest he will also be sidelined for his country's bid to reach the quarter-finals next week.
Brazil will face Portugal, Ghana, South Korea or Uruguay in the round of 16. The worry is that the ankle injury Neymar suffered in the opening game against Serbia is more serious than the slight sprain medics initially diagnosed and that there may be ligament damage.
