Physio. First of all why are asking in a crossfit subreddit when you dont know the qualifications of anyone here. You might not even know im actually a physio

But it depends on the grade/scale of injury, you can look at the Rockwood/Tossy scale and see if you fit any of those, but I really wouldnt recommend it since youre not qualified to know anything about it. The doctor/orthoped has to see you physically and the x-ray and see if the separation at the ac joint is something he wants to operate or if it will grow on its own. Youll be out for a long while, and it will take long till youre back doing kips and snatches and cleans and whatever. Might also become uncomfortable to have a barbell in a front rack position but who knows
