I would say ever. By this point he's probably as recovered as he'll ever be. That labrum is something where the damage can be mitigated but can never really be repaired. It stabilizes that whole hip joint so when it gets out of whack everything from your glute to your groin will hurt, and you can get out of whack simply by sitting down wrong or turning your body, so its hard to imagine someone feeling confident playing football at a high level.
Granted he's gotten more focused care than I ever did, but they basically only did conservative treatment with him. I went through physical therapy to help the surrounding muscles compensate and I'm sure he did as well. One has to just look at basketball player Isaiah Thomas, who tore his labrum with the Celtics and has scarcely played since, to see how little they understand about how to really fix this injury still and how devastating it can be to high level athleticism.
