Everything you need to know about the blockbuster rematch as two of the pound-for-pound best once again go toe-to-toe, live on Sky Sports.
Background
It is finally time for the rematch billed 'no excuses' where Andre Ward and Sergey Kovalev will once again battle to stake their claim for pound-for-pound greatness.
First time around, the mouthwatering unification showdown seemed to have it all, world titles, unbeaten streaks and the rare moment that two of boxing's best fighters would meet in the ring - something that too often fails to materialise in the sweet science.
But now, after a razor-close first fight that narrowly went the way of Ward, a genuine rivalry has developed and the Las Vegas rematch is shrouded in animosity.
Russia's Kovalev stormed out of Thursday's press conference, and will be looking to reclaim his WBA, WBO and IBF titles on Sunday morning while avenging the only defeat on his knockout-heavy record.
Olympic gold medallist Ward, unbeaten as a professional, will have his own plans to win in a more convincing fashion, consolidating his position as one of the world's very best elite fighters, removing any doubt that masked his first victory.
That first controversial fight failed to result in any real pure conclusion as to who truly is the number one light-heavyweight, so will a score finally be settled? Or are these two great champions almost perfectly matched? Things will finally become clearer in the epic showdown this Sunday morning.
