After Conor smacked Nate's fist, people noticed Nate clutching his right hand ... and several media outlets speculated that he suffered an injury that could put the fight in jeopardy.
But deeply connected sources tell us, "Nate is fine and ready to fight ... he didn't even see a doctor because he wasn't hurt."
Translation -- the fist escaped unscathed.
IT'S (almost) TIME!!!!
