MotoGP world champion Marc Marquez will miss the Czech Grand Prix after a second operation on a broken arm.
The Repsol Honda rider had surgery two days later but damage to the titanium plate used to fix his humerus prompted a second operation on Monday.
On Tuesday, the team announced Marquez would not ride in the Czech Republic “in order for him to recover more”.
Test rider Stefan Bradl will take his place at Automotodrom Brno on Sunday.
Marquez was expected to be discharged from hospital in Barcelona within 48 hours of the surgery.
“The titanium plate has been removed and replaced by a new fixation,” said doctor Xavier Mir.
“An accumulation of stress in the operated area has caused the plate to suffer some damage.
“Now we have to wait 48 hours to understand the recovery time.”
Frenchman Fabio Quartararo has won the opening two races of the Moto GP season and tops the driver standings on 50 points, with Marquez yet to register a point.
