Andre emphatically answers doubts.

Ward conquers Kovalev in Vegas rematch with eighth-round TKO

LAS VEGAS - Andre Ward vowed he would leave no doubt this time around. He didn't, turning the tables on a big puncher and stopping Sergey Kovalev in the eighth round on Saturday night to win their light-heavyweight title rematch.

The undefeated Ward turned the fight around with a big right hand that wobbled Kovalev, then swarmed all over him. Kovalev was in the neutral corner and Ward was landing shots to the body when the Russian sat on the ring rope and referee Tony Weeks signaled an end to the bout at 2:29 of the eighth.
