Seven-time world champion Valentino Rossi may miss the Japanese MotoGP Grand Prix because of radiation concerns following the earthquake and tsunami in March.

He said: "I really don't think I'll go to Japan. I was hoping that the championship organisers would make the right decision, but that hasn't been the case and now we've got a serious problem."

The race is set for 2 October at Motegi, north of Tokyo but several hundred miles south of the worst-hit areas.
