Andre Ward v Sergey Kovalev II live on Sky Sports after Paul Smith v Tyron Zeuge

Highlights of the first exciting clash between Sergey Kovalev and Andre Ward

Andre Ward and Sergey Kovalev meet for a second time in the early hours of Sunday, a rematch billed 'No Excuses' after their first fight spawned such a bitter feud.

America's Ward will defend the WBA, WBO and IBF light-heavyweight titles against Russia's Kovalev, the previous holder of those belts, at 2am on Sunday morning live on Sky Sports 1 HD from Las Vegas.

Yet it was Kovalev who landed the first fight's most decisive punch, sending Ward to the canvas in the second round, only to see the judges unanimously favour the American. Kovalev's unbeaten streak went up in smoke but his reputation remained firmly intact and, seven months later, he has an opportunity to avenge his only loss.
