Habsburg was among a number of Alpine drivers testing the Alpine A424 LMDh car at Aragon on 27 March when he suffered a crash at Turn 7, prompting a visit to a nearby hospital for check-ups.
After returning to his home country of Austria the following day, he underwent further scans that revealed the full extent of his back injuries - although the doctors concluded that there was no neurological impact from the incident.
The 26-year-old has begun his recovery treatment, but it remains unclear if he will be fit enough to take part in the 6 Hours of Imola on 21 April.
Should the Austrian driver be unable to race in Italy, Alpine could call in factory Mercedes racer Jules Gounon, who was announced as its reserve driver in February this year.
“On the afternoon of March 27, 2024, during the A424 test session in Motorland (Aragon), driver Ferdinand Habsburg had an accident at Turn 7,” Alpine said in a statement issued to Autosport.
“The cause of the accident is currently under investigation.
“Ferdinand was taken to the hospital in Alcaniz for examinations and was discharged in the evening.
