LAS VEGAS - A bloodied Juan Manuel Marquez rallied to knock out eight division champion Manny Pacquiao with one second left in the sixth round on Sunday to win the fourth fight of their epic boxing rivalry.
The 39-year-old Mexican, who suffered a broken nose and possible concussion, sent Pacquiao face first to the canvas, giving him his first victory over the Filipino superstar.
"I got hit with a punch I didn't see," Pacquiao said.
Marquez knocked Pacquiao down in the third round then ended the fight with a overhand right that hit the advancing Pacquiao flush, sending him down hard.
Pacquiao, who suffered his second consecutive loss, landed under the ropes and lay there for a couple of minutes before getting up and returning to his corner.
Pacquiao was taken to the hospital after the fight for repairs.
The shocking ending stunned the crowd of 16,348 at the MGM Grand Garden arena as Marquez had held his own in their first three fights but had never knocked down Pacquiao until Sunday night.
"I was going to retire last year. Now I feel great that I leave no doubt in the way I got this victory over Manny," Marquez said. "I was counter punching him. I got under his guard, threw the right hand when he tried to punch me."
Pacquiao said he would like to fight Marquez again.
"I am going to rest and come back to fight. I would go for a fifth," he said.
