When I had my shoulder work done (labrum repair and removal of some cartilage, outpatient arthroscopic) it was 6 weeks to get out of the sling, and another few months before I was anywhere close to back up to speed. I certainly wouldn't push it, especially with the position our shoulders are in while belly flying.
YMMV, of course.
