Terence Crawford took all the drama out of his fight against Julius Indongo, and he did it fast.

Now Crawford is the only undisputed world champion in professional boxing.

Energized by his huge home-state following 45 minutes from his Omaha base, Crawford stopped Julius Indongo in the third round Saturday night to claim all four major belts at 140 pounds.

The fight was the first four-belt unification bout since 2004, when Bernard Hopkins stopped Oscar De La Hoya to claim all the belts in the 160-pound division. Crawford came in with the WBC and WBO belts; Indongo, from Namibia, was the WBA and IBF champion.

''It means everything,'' Crawford said. ''When you start boxing when you're 7 years old, that's your dream to become world champion - and after that you want to become something bigger than world champion. You just don't stop there. You go to the highest level possible.''

Crawford's work at 140 pounds probably is finished. A move to 147 looks imminent. Promoter Bob Arum of Top Rank said the plan is for Crawford to go with him to Australia for the expected November rematch between Jeff Horn and Manny Pacquiao. Arum wants Crawford to fight the winner.

''I'm all for it,'' Crawford said.

The 29-year-old Crawford was as dominant as ever against Indongo, a 34-year-old from Namibia who was fighting in the United States for the first time after making a rapid ascent to champion.

Though Crawford was a heavy favorite, Indongo had height and reach advantages that caused his camp some concern.

But Crawford sent Indongo to the canvas with a right to the body in the last minute of the second round and just missed with a massive left hook before the bell. At that point he was in firm control.

Midway through the third round, Crawford caught Indongo with a left hook to the body that put him down writhing in pain.

''We knew the body was going to be open, being that he swings so wild,'' Crawford said. ''We felt we could catch him in the middle of his punches. That's what we worked on in the gym.''
