• Six-time MotoGP winner Marc Marquez suffered a crash in the opening grand prix in Jerez
• The Spanish rider underwent surgery on his right arm and a titanium plate was inserted into it
• It's not known when the Honda rider will return to racing
Reigning MotoGP world champion Marc Marquez underwent a successful operation on his arm Tuesday after crashing in the season-opening race in Spain, but his return date is unknown.
Honda said Marquez would remain in a Barcelona hospital for up to 48 hours after a titanium plate was inserted into his right arm during surgery.
"His aim is to return to the 2020 World Championship as soon as possible with an expected date becoming clearer soon," the team added.
The 27-year-old Spaniard, a six-time winner of the MotoGP world title, fell heavily after losing control of his bike and sliding across the infield gravel during Sunday's Spanish Grand Prix in Jerez.
Marquez was taken away from the track in an ambulance, and later diagnosed with a broken right humerus.
He is unlikely to take part in this weekend's Andalucia Grand Prix, to be held on the same Jerez track. Compatriot Alex Rins and Britain's Cal Crutchlow could also miss the second race of a season delayed and truncated by the coronavirus pandemic.
The next event on the calendar after the Jerez double-header is the Czech Grand Prix in Brno on August 9.
Marquez said: "Hello everyone! The operation went well and I am feeling better! Smiling face with open mouth Thanks to Dr. Mir and his entire team. Looking forward to starting recovery! Thanks for the messages of encouragement!"
