Juan Manuel López vs. Rafael Márquez

Juan Manuel Lopez vs Rafael Marquez was a boxing match that took place on November 6, 2010. Juan Manuel Lopez was the WBO's featherweight champion at the time, and the fight was highly anticipated due to the history of competition between Mexican boxers and those from Puerto Rico.

The match took place in Las Vegas, Nevada. Lopez was able to retain his world title by winning with an eighth round technical knockout.

The fight between Juan Manuel Lopez and Rafael Marquez was originally scheduled for September 18 but postponed due to an injury Marquez sustained on his right thumb. The fight was rescheduled for November 6, which was Lopez's second defense of his WBO title and was broadcast on Showtime.

The fight
Marquez lost the fight in the 8th round by TKO after he was unable to continue due to a shoulder injury. Marquez had chosen to proceed with the bout even though he suffered with a right shoulder injury before the contest because he did not wish to cause a second delay. It was later revealed that Marquez had suffered a hairline fracture in his right shoulder blade during the fight and would require six months to recover from the injury. Despite the loss Marquez expressed his eagerness to face Lopez in a rematch.
