I actually snapped mine mate and didn't realise until the swelling went down 5 weeks later. It remains missing to this day (after 11 years)How long is the recovery? Sounds pretty bad!
With instant treatment like Alisson will receive I would imagine a bad pull would be around a month, a slight tear around six weeks and a total snap probably 3 - 4 months.
Only my thoughts, I have no idea of the reality of any of those situations since I never got mine fixed.
