British superstar Amir Khan (31-4, 19KOs) was well aware of the danger involved when he agreed to move up in weight, by eight-pounds, to a catch-weight of 155-pounds to challenge WBC middleweight champion Saul 'Canelo' Alvarez (47-1-1, 33KOs).

This past Saturday night at the newly built T-Mobile Arena in Las Vegas, Khan felt the full wrath of Canelo's advantages in size and power with a one-punch brutal knockout in the sixth round.

Khan did very well in the fight and frustrated Canelo in the first four rounds. The Mexican puncher was starting to find his range in the fifth round of the fight.

Khan is not upset with the ending. He wants to continue his career and believes that a long fight filled with punishment would have likely ended his professional career.

He believes that it's better to get stopped from a single blow than take a severe beating from a much bigger man for several rounds. This was the third knockout loss in Khan's career. He was brutally knocked out in one round by Breidis Prescott at lightweight, stopped in four rounds by Danny Garcia at junior welterweight, and now Canelo at middleweight.

"I’m glad I got knocked out because I didn’t take that much punishment. I got hit with the one big shot and I’m done. If you look at the fights that I’ve been knocked out in, they’ve been early. I’ve been hit with the one big shot, where as fighters have taken punishment after punishment and stood there. That could ruin your career," Khan said.

“Maybe it is good in a way that I'm not taking a beating for 12 rounds because I might have been retired by now. I've seen fighters take long, long beatings. They're never the same again. Getting knocked out early is better than taking a beating all fight. Obviously I know I got hit by a big strong guy."
