The bout airs from the Air Canada Centre in Toronto, Canada live on Showtime.

Jack, who claimed the WBA regular light heavyweight title vs. Nathan Cleverly last year, is 22-1-2 in his career with 13 wins via knockout.

“This is the first camp that I haven’t had any injuries or felt sick at all during,” said Jack. “This is definitely one of the best, if not the best, camp of my career. We’ve watched film, kept a strict diet and really focused this camp on gearing up toward fight night.”

Following his triumphant run in the 168-pound division that included a title, Jack went up to 175 and bested Cleverly. He later relinquished the belt to approach the fight with Stevenson.

“I asked for the Adonis Stevenson fight a long time ago and the Cleverly fight got me there,” said Jack. “We’ve been talking to Floyd a long time about this fight. He’s a man of his word and he always said that I was going to fight Stevenson. I’m grateful for what he’s done and now I just have to take advantage of the opportunity.

“Adonis is definitely my toughest opponent on paper, but that doesn’t really mean he will be the toughest on fight night. Adonis has always fought everyone put in front of him and I respect that. He’s definitely a good fighter, but I’m a better fighter.

Jack vs. Stevenson is part of the split-site event that begins at 10 p.m. ET and also features Gary Russell Jr. vs. Joseph Diaz from the MGM National Harbor in Maryland.
