Amir Khan swore to be impressive in his first welterweight fight, and he was. Luis Collazo had nothing against him as he was knocked down three times and his agony was just prolonged as the fight ended in a majority decision.

Khan lost out to Marcos Maidana to fight Mayweather, but made the best out of his spot at the top of the undercard for the Mayweather-Maidana card by beating and bloodying Collazo.

''People want to see that fight between me and Floyd,'' Khan said.

Khan, who pushed himself to the limit by starving himself to make 140 pounds, was careful with Collazo, but used his hand speed from the outside to land right hands to the head from the first round on. He dropped Collazo with a right hand in the fourth round, then dropped him twice in the 10th round.

Collazo finished the fight, but he was beaten up badly and was bleeding from a cut by his right eye and his face was swollen from Khan's right hand. Two judges scored it 119-104, while the third had it 117-106.

Khan's dominance was shown in punch stats that showed him landing 264 of 692 to 140 of 511 for Collazo.

''I had to hang in there,'' Collazo said. ''You have to take me out, that's what it's all about.''

Khan, who improved to 29-3, supposedly was going to be fighting Mayweather instead of Maidana, according to Yahoo! Sports. He gave up a title fight in December to wait for Mayweather, but didn't get picked for the fight despite winning an online poll conducted by Mayweather.

''It was very hard because Collazo is really awkward,'' Khan said.

Meanwhile, Adrien Broner came back from his only professional loss to win a lopsided decision over Carlos Molina in a 140-pound bout.

Broner was simply too fast for Molina, who pressed the action but was consistently beaten to the punch. Broner never seemed to damage Molina, but won all 10 rounds on one scorecard and won easily on the other two.

''As you can see I didn't have any trouble,'' Broner said. ''It was sparring on national television.''
