Amir Khan Knocked Out By Canelo Alvarez In Sixth Round

LAS VEGAS (AP) — Canelo Alvarez got on his knees to check on Amir Khan after knocking him unconscious with a big right hand in the sixth round of their title fight.

Then he went over to check on some future business with fellow middleweight champion Gennady Golovkin, who was watching ringside.

It's a fight both Golovkin and boxing fans have been waiting for to happen, though the weight could be an issue. Alvarez wants the bout to be less than the 160-pound middleweight limit, while Golovkin, who holds his own piece of the middleweight crown, vows to fight at his best weight.

"I am old school," Golovkin said just before the fight. "Middleweight is 160. I respect the sport of boxing."

Against Khan, Alvarez needed only one big right hand to turn a close fight into a smashing knockout that left the British challenger out cold on his back in the middle of the ring.

Struggling with Khan's speed, Alvarez unleashed a long right hand that send Khan backward on the canvas, where referee Kenny Bayless didn't even bother to count him out at 2:37 of the sixth round.

Alvarez retained his piece of the middleweight title, but it was not without some nervous moments for his fans who packed the new T-Mobile Arena on the Las Vegas Strip. Khan was more than holding his own in a tactical fight when the right hand suddenly ended it.
