Terence Crawford produced a supreme performance to become the undisputed super-lightweight champion, while Dillian Whyte edged closer to a world title shot.
In a clash between champions for the undisputed WBA, WBC, IBF and WBO jr welterweight world titles Terence Crawford and Julius Indongo battled for history.
Crawford landed the bout's first meaningful punch, a counter left hand, about a minute into the first round and looked more comfortable than the frenetic Indongo, who was bolting in and out but not connecting on any shots.
A crowd of more than 12,000 looked on as Crawford became the first boxer to hold four title belts at once since 2005. Sound off in the comments section below with your thoughts.
The end came in the third when Crawford landed a hurtful left hook to the body, flooring Indongo, who was unable to beat referee Jack Reiss' count at 1:38 of the round.
Crawford has now cleaned out light-welterweight and is widely expected to move up to welterweight to face the challenges that await in one of boxing's traditional marquee divisions.
Terence Crawford KOs Julius Indongo, unifies four major titles
The fight began with Crawford boxing as a southpaw, mirroring the lefty stance of Indongo.
The fight continued what has been a recent boxing renaissance, with a number of brilliant young fighters and outstanding veterans who have combined to make 2017 one of its best years in recent memory. "Everything we practiced in camp it came out in the fight", Crawford said.
"I feel great. I feel like I hardly even fought", Crawford said. He dropped Indongo in the second with a left to the head and a right to the body, and that was a portent of what was to come.
"Belts matter and I am the only world champion at 140lbs - it is a big deal to me".
Crawford still has time on his side and can afford to wait for the victor of this likely rematch, however an interim fight in the mean time would be beneficial in adjusting to the new weight at 147lbs.
