I didn't break my clavicle when I was cut off and id a endo but put my right hand down and separated my shoulder. It was grade two so no operation unless I want to get rid of the bump. Put me in a sling for two weeks with sleeping being the hardest part. It took me a good six weeks before I could get on the bike and put pressure on the shoulder and believe you will have the same feeling. At about eight weeks all was pretty good and riding without to much discomfort.
Good luck.
