The Isle of Man TT organisers say they are "deeply saddened" to learn of the death of sidecar competitor Olivier Lavorel.
The Frenchman was seriously injured in a crash at this year's TT races, which also claimed the life of his teammate Cesar Chanal.
Mr Lavorel, who hailed from Sillingy, was airlifted to hospital in Liverpool following the incident at Ago's Leap on June 4 before being transferred to a hospital in France later that month.
