Julio Cesar Chavez Jr. posted a video of himself urinating on a picture of Jake Paul before their press conference Thursday in Anaheim, California.

Paul appeared annoyed by the proceedings and responded by slapping a piece of paper in front of Chavez’s seat at the dais with a message that read: “I will be getting knocked out.”

Chavez removed the paper and unveiled a custom shirt in Mexico’s flag colors that claimed he is Paul’s daddy. Chavez gifted Paul the shirt, who retaliated by heaving it and hitting him in the head.

As has become customary at Paul’s events, there’s plenty of pomp and circumstance before the punches officially start flying, which in their case will be Saturday at Honda Center to headline a DAZN Pay-Per-View show.

“He’s a great fighter,” Paul said. “I like big names. I like legendary names, and he’s on my path to world championships. He’s coming prepared and he’s saying this is the hardest he’s ever trained. It’s a very tough test, but I am here to challenge myself and do big things in the sport and make a title run after I beat him on Saturday.”

Paul (11-1, 7 KOs) envisions a statement win against Chavez (54-6-1, 34 KOs, 1 NC), a faded former middleweight titlist who hasn’t had a meaningful win since 2012, will switch his career into second gear.

“To become a world champion, I need to be ranked,” Paul said Wednesday during his media workout. “That’s what this fight is all about. Beating Chavez in a great fashion, we’ll see where the WBA and WBC rank me, and then hopefully I’ll be able to go for a world title.”

Paul believes he’ll get Canelo Alvarez’s attention once he wins a cruiserweight title, a division controlled by champions Jai Opetaia (The Ring, IBF), Gilberto Ramirez (WBA, WBO) and Badou Jack (WBC).

“The Canelo fight has to happen at some point,” Paul said.

MVP Promotions CEO Nakisa Bidarian is tasked with maneuvering Paul’s career. Bidarian said after spending nearly six weeks earlier this year negotiating to face Alvarez in May, the deal fell apart at the 11th hour when he signed a four-fight deal with Riyadh Season.

Paul and company immediately moved on to Chavez, who was an option all along. Chavez last fought and beat Uriah Hall by decision on the undercard of Paul’s knockout win against Mike Perry in July.

That was his first fight since leaving rehab. Paul moved on to face Mike Tyson in a lucrative yet lackluster fight in November.

“The Chavez fight has been a fight that has been strategically looked at for the last two years,” Bidarian told The Ring. “I’m hoping Julio gives Jake the toughest fight of his career. Everything we’ve seen from Julio is that he’s extremely focused. This would be the perfect righting of his wrongs. He’s as motivated as ever and is Jake’s most dangerous opponent ever. If Jake beats Julio, you can’t deny it anymore.”

Bidarian said Paul wants to do massive global events that energize boxing while getting mainstream audiences excited, all while building his skill set against credible opponents as he chases a world title.

“The onus is on Jake to show that he’s for real on Saturday night,” Bidarian said. “I hope he showcases his boxing skills. If Jake puts on a great performance, why wouldn’t you rank the guy?”
