From mcnews.com.au:

British rider Craig Jones has succumbed to the massive head injuries he sustained during a high speed fall during the Brands Hatch World Supersport round in Kent.

Jones was battling for the lead at high speed before losing traction exiting the fast Clarke Curve. Jones fell heavily and then was struck by another machine following close behind. The following rider, Andrew Pitt, was left with no time to even consider taking evasive action, let alone the chance of successfully performing such a manoeuvre.

Jones received immediate medical attention at the scene and was put in a drug induced coma prior to being air-lifted to Royal London Hospital. Despite the best care Jones unfortunately failed to recover from his injuries and passed away in hospital.
