Jake Paul is preparing for what he sees as the highlight of his boxing career.

On June 28, the YouTuber-turned-boxer will meet former middleweight champion Julio Cesar Chavez Jr. in Southern California, a fight that can propel Paul's reputation to stratospheric heights in the combat sports universe.

Jake Paul's Toughest Test Yet

Paul, who defeated Mike Tyson in their November bout, is confident about his upcoming fight in the ring.

In a recent TMZ Sports interview, he confidently stated that the fight would be his "breakout performance."

"It's going to be a tough fight, you know. Someone's going to get embarrassed, and it's not going to be me. But I'm training harder than ever. I know this is my toughest opponent yet. Maybe not the biggest name opponent, but it's still going to be a super, super good fight."

Although Chavez Jr. is probably not as hyped as some of Paul's previous fighters, he is far more experienced. The 39-year-old Mexican boxer and son of boxing legend Julio Cesar Chavez Sr. has 64 pro fights under his belt, so he's a strong opponent.

Over the years, Chavez Jr. has faced criticism for his inconsistent training and questionable work ethic. However, Paul claims that won't be the case this time.

That level of commitment adds an extra element of intensity to what is already proving to be a hot match. For Paul, the fight means more than just a victory. For the 28-year-old boxer, it's a steppingstone on the way to a genuine world title shot.

Holly Holm Returns to Boxing Under Jake Paul's Promotion

Jake Paul is not only working on his own career. He's also breaking boundaries in promoting boxing, particularly women's boxing. UFC legend Holly Holm returns to the ring after a long hiatus under Paul's Most Valuable Promotions (MVP).

Holm, who famously knocked out Ronda Rousey in 2015, will square off against Yolanda Vega in a 10-round boxing fight, her first boxing bout since 2013.

Paul lauded Holm's signing as one aspect of his larger plan to raise the profile of women's boxing. With stars like Amanda Serrano already on his roster, Paul is constructing a formidable stable of female fighters.

Is Claressa Shields Coming to MVP?

Paul would not rule out that undisputed champion Claressa Shields might join the MVP someday, even though there has been tension between the pair in the past.

Shields has previously been critical of Paul, but Jake is open to doing business. As usual, the young pugilist is always down to work with "real talent" despite the differences.

Meanwhile, a Bad Left Hook report tells us that Ukrainian professional boxer Oleksandr Usyk's team is considering a future MMA fight with Paul.
