Alex Marquez, younger brother of MotoGP champion Marc Marquez, has undergone shoulder surgery.

The Estrella Galicia 0,0 rider, who claimed one victory and fourth in the world championship during his rookie Moto3 season, had been suffering from a 'recurring dislocation' of the joint.

During the operation at the Hospital Universitario Quiron Dexeus in Barcelona, doctors "stabilised the shoulder by introducing a bone block and reconstructing the anterior shoulder ligaments."
