Jake Paul faces toughest test yet in Julio César Chávez Jr.

The intrigue: Chávez, 39, is a former middleweight champion, and likely the stiffest competition Paul has faced in his young boxing career.

By the numbers: Paul has gone 11-1 since moving from viral social media star to boxer in 2020. His lone loss was a split decision to Tommy Fury in 2023.

• Paul's last fight against Mike Tyson drew 108 million global viewers, making it the most-streamed sporting event ever, according to Netflix.

Yes, but: Many boxing purists still refuse to take Paul seriously, considering he has mostly fought aged boxers or former mixed martial arts stars.

The odds: Paul is a huge favorite on most sportsbooks. Former boxing champion and ESPN analyst Timothy Bradley agrees, picking Paul to win but warning against Chavez's "wicked" left hook.

• "It's fast, automatic and effective, and if Paul doesn't see it coming, we could see him looking up at the lights from the canvas."
