Former heavyweight world champion Lennox Lewis has tipped Andre Ward to secure victory when he fights Sergey Kovalev in Las Vegas on Saturday.

American Ward has won all 30 of his professional bouts to date, although he has spent the majority of his career competing in the super middleweight division.

The 32-year-old has successfully made the step-up to the light-heavyweight division this year however, with a victories over Sullivan Barrera and Alexander Brand, and he will now take on Russian fighter Kovalev for the WBA, IBF and WBO titles at the T-Mobile Arena.

Kovalev has also never tasted defeat in his career, and former heavyweight champion Lewis is anticipating a fantastic fight between the pair, although he has tipped Ward to secure the victory.

“You’ve got two undefeated guys, you’ve got Andre Ward moving up a weight class and you’ve got Kovalev who is the king of this class, both of them have been at the peak of their weight class and yet they are meeting,” Lewis told Sky Sports.

“I think it’s a style match-up because both have different styles, but I may give the edge to Ward, although he is taking on a bigger and heavier guy.”

Lewis believes both fighters are capable of delivering a knock-out blow during the fight, and he has praised both men for their preparations in the build up to the contest.

He added: “Both of them have knock-out power, so we are in for a serious fight. I believe this is the pound-for-pound title. Both of them are very gifted at their craft and both of them take it very seriously.”

Ward is available at 1.75 to win the fight, while Kovalev is priced at 2.10 and the draw is on offer at 26.00.
