Mexican great Saul ‘Canelo’ Alvarez further added to his legacy by taking the WBO light-heavyweight crown from Sergey Kovalev with a devastating 11th-round knockout in Las Vegas.

Middleweight king Canelo, 29, had stepped up two weight divisions to face the 36-year-old Russian.

It proved a close fight which failed to ignite before an explosive combination from Canelo ended Kovalev’s night.

Canelo has now won world titles in four weight divisions.
