Belgian co-driver Jurgen Damen has died as a result of the injuries sustained in an incident in the Qatar round of the FIA Cross Country Rally World Cup.
The 42-year-old was seriously injured when the car driven by Rene Kuipers crashed during Monday's first stage of the Qatari event.
Dutch media reports Damen broke his neck in the accident. He received on-site medical attention before he was transferred to hospital in Doha, where he succumbed to his injuries.
"The FIA wishes to extend its most sincere condolences to the family and friends of Mr Damen, as well as team mates, fellow competitors, officials and event organiser," said the FIA in a statement.
"The thoughts of the broader motor sport family are firmly with them all in this deeply distressing time."
The FIA said an investigation into the incident is taking place in conjunction with all relevant authorities and officials.
Damen was an expert co-driver with several years of experience in rallying, including several outings in the Dakar Rally.
From 2012 to 2014, he co-drove with Peter Versluis at the MAN team in the trucks category, winning the final stage of the 2013 event before notching up a further success the following year.
Damen switched to Iveco for the 2015 Dakar, co-driving Gerard de Rooy on their way to ninth place overall.
