Sorry, but Keith Thurman only has himself to blame
I remember a year ago he did an interview with Fighthype or Fighthub and said "I'm not just going to comeback for just any fight" and also said "For a fighter of my caliber, I can't take a step backwards and not be fighting on main events". Over played his hand. He should have been taking fights to get his rhythm back, to get his body used to Boxing again. No doubt his injury is his body not being able to take the ramp up in training camp
1 fight in 4 years is terrible. Keith's body retired for him
It's like his body said "Nah nikka. We don't do this no mo'

Just betrayed him.
