In the 1956 Giro d’Italia, Fiorenzo Magni crashed during stage 12 and broke his left collarbone.
Magni refused hospital treatment and continued the race with his shoulder bound with an elastic bandage.
The picture shows the Italian rider during stage 13 holding a piece of rubber inner tube (attached to his handlebar stem.) between his teeth for extra leverage.
I would say you are back on your bike within a week or so.
Good luck!
