This would explain quite a bit.
Coming out of Jon Jones successful light heavyweight title defense against Vitor Belfort in the main event of UFC 152 last night (Sept. 22, 2012) in Toronto, Ontario, Canada, more than a few fans and pundits, including the FUEL TV post-fight analysis team consisting of Kenny Florian and Dominick Cruz, criticized "The Phenom" for his strategy.
Indeed, the Brazilian frequently pulled guard and seemed hesitant to let his hands go, which seemed odd considering his strongest weapon throughout his long career has been the speed and power in his two fists.
So what gives?
As it turns out, Ron Kruck got the word from the man himself and a training camp injury may be to blame.
Vitor Belfort just told me that he fought with a broken hand suffered in training. As tough as they come.
Despite this disadvantage, Belfort very nearly submitted Jones with an armbar in the first round, locking it in so deep that "Bones" complained his arm was numb during the post-fight interview. In fact, it's probably not out of line to say, Belfort put up a better fight than any challenger for the title before him.
The fact that he did so after having worked through a broken hand? Incredible.
