Juan Manuel Marquez knocked out Manny Pacquiao with one second remaining in round six of their welterweight fight in Las Vegas this morning.
It was the fourth time the pair have fought, following a draw in 2004 and controversial wins for Pacquiao in 2008 and 2011.
After a cagey opening two rounds, Marquez dropped the Filipino with an overhand right in round three.
The two rivals then started to exchange a string of exciting combinations, with Pacquiao sending the Mexican to the canvas in round five.
With Pacquiao starting to gain the upper hand in round six, Marquez looked like he could go down again, before recovering to knock Pacquiao out with 2.59s on the clock.
