Andre Ward stops Sergey Kovalev to win light heavyweight rematch
American fighter swarms all over Russian opponent in eighth round

American Andre Ward stopped Sergey Kovalev in the eighth round to retain his IBF, WBA and WBO titles on Saturday in an entertaining rematch of their light heavyweight fight seven months ago.
The unbeaten Ward hurt Kovalev with a right hand that buckled his knees and then finished him off on the ropes with a series of body shots around the mid-section at the Mandalay Bay hotel and casino.
Referee Tony Weeks stopped the fight with 31 seconds left in the round with Kovalev kneeling down from what he said was a low blow by Ward.
Ward improved to 32-0 as he held onto three of the four major boxing belts in the 175-pound fight.
The 33-year-old Ward needed this victory to validate his first win over Kovalev as many felt the Russian won the first fight and that Ward had been given a gift decision by the three judges.
