The unlucky 29-year-old had surgery on his left clavícula on Monday, only 24 hours after the crash, as it was decided to take action as fast as possible to speed up the healing. As it happens, it's not just a simple broken collarbone for Antón. It's a so-called 'refracture', and the Galdakao-native will have two plasma injections with a high amount of growth factors in the coming weeks.
Antón famously broke the same collarbone on stage 13 of the Vuelta a España to the Angliru four years back.
Doctors Elorriaga and Azurmendi of the Clínica Igualatorio Médico Quirúrgio (IMG) San Sebastián in Bilbao performed the surgery.
No time scale has of yet been set on his rehabilitation.
