Marquez suffered a nasty highside crash in the sprint on the final lap and the world champion was thrown off his bike, which cartwheeled through the air before landing beside him.

The Spaniard had planted his right foot on the track just before he was thrown off his bike and the 33-year-old was seen hopping on one leg before he was taken to the medical centre.

“After a medical check and X-ray, Marc Marquez was declared unfit for a fifth metatarsal fracture in his right foot. He will fly to Madrid tonight to undergo surgery,” Ducati said in a statement.

The injury is another blow for the reigning champion who has yet to finish on the podium this season.

Marquez sits fifth in the standings, 51 points behind Aprilia’s championship leader Marco Bezzecchi.
