British superstar Amir Khan (31-4, 19KOs) is confident that he'll return even stronger after Saturday night's crushing defeat.

Khan dared to be great by moving 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).

Before a crowd of over 16,000 fans at the T-Mobile Arena in Las Vegas, Khan was knocked unconscious by a huge right hand in the sixth round.

This was the third knockout loss in Khan's professional career.

In 2008, he was knocked out in 54 seconds by Breidis Prescott in a light heavyweight contest. Four years later, in 2012, he was stopped by Danny Garcia in four rounds after being dropped three times. Many would argue that his knockout at the hands of Canelo - much bigger and stronger than Prescott or Garcia - was the most devastating loss of his career.

After each knockout loss, Khan was able to regroup and rebuild his career within a few fights. He's positive that he'll be capable of doing the same thing when he returns in the fall.

Khan, who is moving back to 147-pounds, has already stated that he intends to have about three to four more fights before retirement. Once his medical suspension has expired, he wants to return in the fall - hopefully in a rematch with Garcia. Khan is still the mandatory challenger to Garcia's WBC welterweight championship.

"I've been knocked out before and I have always come back stronger," Khan said.

“I know I will come back stronger from this. I've got it in me to come back from being knocked out like that.

“I know I was doing everything fine. My boxing skills are still there.”
