The No. 91 Herberth Motorsport Porsche 911 GT3 R has been withdrawn from the Hankook 24H Dubai following a heavy accident on Wednesday for Daniel Allemann.
Allemann and the No. 103 PPM Passion/Performance/Motorsports Cupra TCR DSG came together in the second Unofficial Private Test, resulting in the Porsche reportedly upside down according to a report from Radio Le Mans.
The Porsche sustained extensive unrepairable damage.
Allemann was due to share the GT3 Pro-Am class entry with fellow 24H Series veterans Ralf Bohn and brothers Alfred and Robert Renauer.
Herberth has two other GT3-spec Porsches still entered for the race, including the No. 92 car that is entered in the overall category.
The No. 199 AC Motorsport Audi RS 3 LMS DSG has also been withdrawn from the weekend following a separate accident on Wednesday.
It has resulted in an 81-car entry list for the 24H Series season-opener.
