Australian superbike legend Troy Bayliss has suffered a broken leg in a crash while competing in a AMA Pro Flat Track event in America.
The 46-year-old three-time world superbike champion was taking part in the semi finals at Sacramento Mile, California, when he collided with a catch fence at high speed.
Bayliss was taken to a nearby hospital where it was confirmed he had suffered a fracture at the base of his right fibula.
The race was the second of five scheduled appearances in the popular American dirt bike racing series.
Bayliss will cut his trip to America short as he intends to fly back to Australia for surgery.
The Taree-born rider made two appearances in the World Superbike Championship this year as a replacement for the injured Aruba Ducati rider Davide Giugliano.
This latest injury looks set to end any chances of Bayliss returning to the saddle for more races in the near future.
