Once upon a time, the “Krusher” that is Sergey Kovalev suffered his first, and to date, his only knockout loss in the four-squared ring.

On Nov. 19, 2016, two worlds will collide in the guise of reigning and unified light heavyweight champ Kovalev, and erstwhile unified super middleweight titlist Andre Ward.

At stake are Kovalev’s WBO, IBF and WBA straps. Also on the line are their respective “O’s,” which by the night’s end, one will surely go.

Since turning pro in July of 2009, Kovalev (30-0-1, 26 KOs) has been a one-man wrecking machine, leaving behind a trail of destruction in his quest for 175-pound supremacy.

The only blemish on his otherwise stellar record is a technical draw against Young Glover in 2011, which occurred due to an accidental foul, thus prompting Glover to discontinue the contest.

That Knock Out:

But first off, Kovalev has tasted the canvas on two separate occasions in the pro ranks, a la Darnell Boone (2010) and Gabriel Campillo (2013).

Furthermore, if reports of GGG flooring Kovalev in sparring are to be taken at face value, well, it lends even more credence to the fact that the Russian heat-seeking missile isn’t an unstoppable force.

That notwithstanding, only one fighter has the honoured distinction of both flooring Kovalev and laying him out. That man is Abbos Atoyev. And though it happened in the amateurs, it still proves one thing; not only can Kovalev be put down, he can also be put out.

Albeit Ward has been knocked down once in the pros, he’s never been KOed in either the pros or amateurs.

All told, will Ward (30-0, 15 KOs) be able to repeat that Atoyev feat when they eventually put up their dukes?

Styles make fights, fighters grow, but the feeling is, this fight (whichever way it goes) will be one for the annals of the sweet science, and a knockout is on the cards, however, it won’t be Ward being counted out.
