The unbeaten Russian will put his WBA, IBF and WBO light-heavyweight titles on the line against Pascal at the Bell Centre on Saturday night, live on Sky Sports.
Pascal risked the wrath of Kovalev by taking off his opponent???s cap as they posed for pictures, prompting an angry response from the champion, who shoved the Haitian across the stage.
The fighters were quickly separated and will renew their hostilities this weekend, with Kovalev keen to cement his status as the no 1 fighter in the division.
???Jean Pascal is a tough boxer and Saturday I will see how tough,??? said the 31-year-old, who has halted 23 of his 26 foes.
???I am not going to say any prediction. This is boxing, anything can happen with a fight.
???For me this fight is very interesting because it is next step in my career, the next test in my career.
???For myself I want to prove who I am on this level, in front in this huge arena, in my first time fighting in a huge arena like this.??? ??
Pascal???s reign as WBC champion was ended by Bernard Hopkins, but he can repair his reputation with an upset win over Kovalev.
???I said the best scenario is to give the fans 12 good rounds and then try to knock him out in the last 15 seconds of the fight.
???I will give 110% on Saturday night, but I cannot predict the future.???
