Jones, the International Boxing Federation super- middleweight champion, and regarded by many as the best pound-for-pound boxer in the world, knocked down Sosa in the second round with a straight right. The Dominican bounced back up, but only to take about 20 unanswered punches before the referee Ken Zimmer stepped in and stopped the bout 24 seconds before the end of the round.
Sosa, furious at the decision, claimed he had not been hurt and pushed Zimmer into the ropes before having to be restrained by members of his corner team. Sosa normally fights at the light-heavyweight limit of 12st 8lb, but the two fighters agreed to split the difference between their usual weights and observe a maximum of 12st 4lb.
"Tonight I showed who's the best fighter in the world pound for pound," Jones said after advancing his career record to 31 straight victories.He added that he used the fight to demonstrate an approach other than his usual, left-handed style. "I used my right hand. I wanted to show a different style. I worked him inside and didn't want to run. I showed power and strength."
Jones reiterated that one of his dreams was still to play professional basketball in America and, as a stepping stone, he would train with the London Towers in February - a move which would take him out of boxing for a couple of months. His other ambition is to fight Nigel Benn,the World Boxing Council super-middleweight champion, but Benn's promoter Don King has already scotched the idea.
