I believe the foot problem was during the camp not in the fight / after it.
Also think it wasn't that bad like a 100% fracture or he would have pulled out.
Maybe he underestimated Luke and he went in there.. and the weight issue maybe a combination of IV ban, injury, new diet.. also he was more around 195 lbs and Luke also wasn't as big as usual so him around 205 lbs (IV ban and he also had some issues).
I believe both fighters used to come in fight night at around 210 lbs before there last fight (of course I'm not in there camps with a scale so its all speculative).
Don't like that (and I'm a fan) Chris always talks after his fights using "this was the worst training camp ever" its a habit at this point.
I didn't hear the wife comments care to elaborate please ? or any idea where to find them ? thanks in advance.
Edit: just saw your top comment hmh strange I tried to look for them but no luck so far.
