MMA veteran Chris Avila to face YouTube star Doctor Mike in boxing match on Jake Paul-Anderson Silva card

The Jake Paul vs. Anderson Silva boxing undercard will feature an unorthodox matchup.

UFC and Bellator MMA veteran Chris Avila will compete against YouTube star Doctor Mike in a four-round, professional boxing match Oct. 29 in Glendale, Arizona, officials told ESPN. The contracted weight will be 185 pounds, and the pair will fight with 10-ounce gloves. An official announcement is expected to be made later Tuesday.

Doctor Mike, whose real name is Mikhail Varshavski, is a well-known social media influencer with more than 23 million followers across platforms and more than 10 million YouTube subscribers.

Varshavski competed in an amateur boxing match back in May, a unanimous decision win over YouTube personality Ian «iDubbbz» Washburn. That event raised $1.3 million for charity, and Varshavski donated his entire fight purse to Ukraine relief. For the Avila fight, Varshavski will donate his purse to the Boys & Girls Club, per officials.

«As a practicing physician, I've taken an oath to 'do no harm,' but when those 'exam' gloves come off and the boxing gloves slide on: all bets are off,» Varshavski said via a statement. «With one win under my belt, I'm hungry to add more. And this pro-fight with Chris Avila could be just what the doctor ordered.»

This will be Varshavski's pro boxing debut, as he joins the likes of Paul as famous YouTubers competing against professional boxers.

Avila is 1-1 as a pro boxer and is an eight-year veteran of mixed martial arts, a longtime member of Nate Diaz's team in Northern California. Most recently, Avila beat Paul sparring partner Anthony Taylor last December in a boxing match via majority decision. Avila is expected to be the first fighter signed to Diaz's new promotional entity Real Fight
