Fell backwards off and went to catch himself. Ended up breaking the bone right below the head of his humourous, separating the shoulder and minor cracks in head of humourous head itself.
Luckily no surgery because break is clean. Placed him in an orthotic soft cast splint thingy for now and will report back in a week. As long as he keeps it immobilized they think he can avoid any surgery.
4-6 weeks if all goes well.
