The fight will go in the books as an 11th round TKO for Emanuel Navarrete, though nary a punch was thrown in the round.
Promoter Eddie Hearn raced to the Nuñez corner in between rounds, out of concern for his fighter and seemingly eager to have them stop the contest.
Referee Benny Rodriguez does it for him as he had the ringside physician once again examine Nuñez. This time, it's agreed that the fight needn't continue.
Emanuel Navarrete wins at 1 second into the 11th round, and is now the unified IBF/WBO 130lbs titlist. Nuñez snapped a 20-fight win streak with the setback as his title stay ends at just nine months.
