The London Olympics has lost one of its biggest star attractions following the withdrawal of the defending men's tennis champion Rafael Nadal because of injury.
Nadal, who was also going to be the Spanish flagbearer at the opening ceremony next Friday, has failed to recover from a knee injury, and he's described his decision as one of the saddest moments of his career.
Nadal won a record seventh French Open title in June but crashed out in the second round at Wimbledon in a massive upset against lowly-ranked Czech Lukas Rosol.
Earlier this month he pulled out of a charity match against Novak Djokovic in Madrid saying he was suffering from tendonitis and needed to rest.
