'The Krusher' put in a report performance to stop Jean Pascal in their World Light-Heavyweight Title rematch after new trainer Freddie Roach pulled his man from the contest in the seventh round.
It was the one sided fight many had predicted. Kovalev's jab was causing Pascal problems let alone the big right hand that followed.
The unified World Champion cut off the ring to perfection, backing his opponent onto the ropes at ease and landing at free will throughout the contest.
After a first round knockdown was ruled a slip by referee Michael Griffin, Kovalev caught Pascal in the third which clearly hurt the challenger.
It was to be round after round of onslaught with all three judges scoring the fifth round 10-8 despite Pascal not even touching down.
Four chopping rights and some fierce hooks to the body almost put Pascal away but to his credit he showed some determination not to go down.
Roach threatened to pull Pascal out, who managed to talk his way into another round but after only throwing single shots enough was enough.
Pascal's eyes were swelling minute by minute and you have to agree it was the right decision from the legendary trainer to pull his new man out of there before the start of the eighth.
Kovalev once again showed why he is one of the most feared boxers on the planet as he looks to a potential unification bout with Adonis Stevenson, who later entered the ring during the post fight interviews or mega fight with Andre Ward.
Sergey Kovalev faces Jean Pascal once more in a rematch of their March 2015 fight live on BoxNation, Saturday 30 January 2016.
Kovalev’s IBF, WBA & WBO Light-Heavyweight World Titles will be on the line at the Bell Centre in Montreal, the scene of Kovalev’s eighth round stoppage over Pascal earlier this year.
You have to favour the defending Champion to put in a repeat performance but Pascal is now trained by renowned trainer Freddie Roach who may employ some fresh tactics.
Roach believes he can take Pascal to the next level having improved Miguel Cotto and Manny Pacquiao under his guidance.
Hard hitting ‘Krusher’ who was the first man to stop Pascal, boasts an impressive KO ratio with 86% of his victories coming inside the distance.
Last time out in July, Kovalev demolished mandatory challenger Nadjib Mohammedi in the third round. Pascal, who featured on the undercard scraped a victory over Yunieski Gonzalez with many fans and pundits alike believing the scorecards were a little kind.
The fight holds the key to unlock some potential huge fights in the division with WBC World Champion Adonis Stevenson eagerly looking on with a potential unification bout in the pipeline to crown the undisputed king at 175lbs.
Stevenson v Pascal would also be a big fight in Canada, mixed with their Haitian background only adds spice to the occasion.
Andre Ward is another piece of the jigsaw having recently moved up a weight and ear marked to fight Kovalev later in 2016.
