The 2026 Catalan MotoGP Grand Prix has been marked by a very severe accident involving Álex Márquez that forced the race to be interrupted with a red flag. The Spanish Ducati rider was thrown off at the entrance to turn 10 of the Barcelona-Catalunya circuit after being affected by a problem with Pedro Acosta's KTM, who was leading the race at that moment.
According to initial reports, Acosta suffered a problem with the rear wheel of his KTM while leading. Álex Márquez, who was riding just behind, could not avoid the situation and ended up flying through the air in a very delicate part of the track, near the protective wall.
Red flag in Montmeló after Álex Márquez's crash
Race Direction immediately showed the red flag to stop the race and allow medical attention to the rider. Márquez's bike was heavily damaged by the impact and several parts ended up scattered across the track.
Italian rider Fabio Di Giannantonio was also involved in the incident, being hit by debris from Álex Márquez's bike. The accident left a scene of enormous tension in Montmeló, although initial reports indicate that Márquez did not lose consciousness.
Álex Márquez was taken to the medical center
Álex Márquez was attended to at the scene of the crash by the championship's medical staff and subsequently transferred by ambulance to the circuit's medical center. The rider was conscious after the impact, according to initial information released from the track. 
The visual severity of the accident necessitated extreme caution. The Gresini rider could not take part in the restart of the race, which was to be held again as the regulatory two-thirds of the planned distance had not yet been completed.
Pedro Acosta's problem that triggered the accident
The origin of the incident was Pedro Acosta's bike, who was leading the race when he suffered a problem with his rear tire. His KTM's wheel appeared visibly deflated and the rider was able to return to the pits with assistance after the race was interrupted.
Álex Márquez was riding close behind the Murcian at that moment and encountered the incident practically on top of him. The sequence ended with a violent crash at turn 10, one of the most challenging points on the circuit when approached with no margin for reaction.
A race marked by tension
The accident occurred after a very intense weekend between Álex Márquez and Pedro Acosta. In Saturday's sprint race, Márquez had beaten Acosta in a very tight duel decided by just 41 thousandths of a second, one of the closest finishes of the season.
This Sunday, both were once again fighting for the lead when Acosta's mechanical problem completely changed the race. The sporting battle quickly turned into a scene of maximum concern on the track.
