Sir Bradley Wiggins could miss the Tour de France because of a knee injury that is affecting his training.
Wiggins became the first ever Brit to win the event last year when he rode to glory with Team Sky.
However Dave Brailsford, Team Sky's Principal, admits that Wiggins is struggling to train because of this latest injury.
"With these setbacks I can confirm that Brad cannot currently train properly and we are monitoring this situation carefully," he told The Guardian.
The injury isn't related to the incident that incurred at the Giro d'Italia when Wiggins fell on a descent and was seen applying ice to his right knee afterwards. The 33-year old had to eventually withdraw from the Giro d'Italia after he suffered a chest infection.
This year has certainly brought Wiggins back down to Earth after such a triumphant 2012. The triple Olympic gold medallist won the Paris–Nice, the Tour de Romandie, the Critérium du Dauphiné, the Tour de France and the time trial at the Olympic Games.
However, the new season hasn't been so successful for Wiggins. He struggled in his first event, the Tour of Oman and finished fourth in the tour of Catalonia.
In the Giro del Trentino he had a mechanical problem while the Giro d'Italia was a nightmare for 'Wiggo.'
Suffering in the cold and wet conditions, he experienced a crash and a puncture before being diagnosed with a chest infection.
Wiggins has been told that, if he is fit for the Tour de France, he would be assisting Chris Froome who is aiming to lead Team Sky to glory.
However, Wiggins has admitted that he would like to win the Tour de France himself if he was going into the event in better form than Froome, raising a potential conflict between the pair.
