Amir Khan was the favorite to face Floyd Mayweather Jr. before Marcos Maidana battered Adrien Broner and flipped the script entirely. Khan was shunted off to the undercard against a dangerous puncher in Luis Collazo, and even though Khan easily won Floyd might still be far away.

Khan, Broner each win--Proposed fight set to happen?

Maidana acquitted himself very well against the pound-for-pound king, using roughhouse tactics and an unrelenting punch output to put himself in a good position to win. One judge even scored the bout a draw, leading to immediate speculation of a rematch.

That has to get under the skin of Khan, who looked as dominant as ever vs. Collazo. With new trainer Virgil Hunter in his corner Khan appeared more careful and rougher in his first fight at welterweight, although he was still rocked a few times.

Floyd Sr. rips Amir Khan's "glass jaw"

"One thing about me training with (new trainer) Virgil Hunter," Khan said. "It's the first time I've spent good time with him. He taught me good things that you can only put to practice in the ring."

Khan's often involved in firefights that involve him catching hard shots and suffering knockdowns. In this bout, he utilized a lot of grabbing and pushing, even losing a point for shoves. Collazo complained post-fight about how Khan's physicality affected him.

"Khan's style was difficult. He kept grabbing me," Collazo said. "I had to hang in there, that's how we do it. You gotta take me out. This is what it's all about."

After getting that win over a quality opponent, Khan made sure to call out Mayweather once again. "I'm the only one to have the speed and explosiveness to give him trouble.

"If you look at my fights, even the ones I've lost, when it comes to boxing, no one can beat us. Floyd's a master class in boxing, but I've never lost when it comes to boxing. It'll be skills versus skills. And I think the youth will take it."

Should Floyd face Khan or give Maidana a rematch? Let us know @SportsWN!
