Craig Jones, the Northwich motorcycle racer involved in a 120mph crash at Brands Hatch on Sunday, died from his injuries yesterday.
The 23-year-old former Hartford High School pupil and Mid Cheshire College student came off the track while vying for the lead in a World Supersports race and appeared to be hit by another bike.
He was rushed to hospital by air ambulance with serious head injuries and was placed in a drug-induced coma to relieve the pressure on his brain.
Jones' team manager at Parkalgar Honda, Simon Buckmaster, said: "It is with great sadness that we learned Craig passed away in the early hours.
"The team's thoughts are with Craig's family and friends at this very difficult time. His family pass on their thanks to all well-wishers."
