I'm surprised by how few have addressed the elephant in the room. Consider where Khabib trains and what seems to happen with alarming frequency with that gym. I have a feeling this wasn't a Hendricks/Gastelum disciplinary issue as much as it was an overtraining/pre existing injury scenario that limited his ability to cut effectively. Cain and DC each pulled out of three fights last year, Rockhold pulled out of two and now Khabib does this. Of course we can't forget that he, Cain and Rockhold have previously endured two year injury layovers as well. I believe that there's a systemic issue at AKA. No other major gym has this problem.
