Back in late October or early November there was a video of him dancing in the locker room after a win and he was hunched over throughout. In the discourse about that it was indicated that he’d recently had another procedure. I don’t think there was ever any official statements or stories (and why would there be? That’s a personal matter that had 0 bearing on the Colts and more than that, it’s no one’s business what procedures he’s had) but that was the scuttle.
