Jarrell “Big Baby” Miller and Lenier Pero meet Saturday night at the BleauLive Theater at Fontainebleau Las Vegas in a WBA World Heavyweight Title eliminator. The winner moves into position as a mandatory challenger at heavyweight. The card is promoted by Eddie Hearn and Matchroom and streams on DAZN.

Miller (27-1-2, 22 KOs) returns three months after a split-decision win over Kingsley Ibeh on January 31 at Madison Square Garden, on the undercard of Teofimo Lopez vs. Shakur Stevenson. It was his first bout in more than a year. His record still carries a 10th-round TKO loss to Daniel Dubois in December 2023 and a majority draw with Andy Ruiz Jr. in August 2024. The 37-year-old Brooklyn native has not fought for a world title since failed drug tests scuttled his 2019 date with Anthony Joshua. He enters ranked No. 9 by the WBA.

Pero (13-0, 8 KOs) is the younger, less-tested fighter with the stronger amateur pedigree. The Cuban southpaw represented his country at the 2016 Olympics and won two Pan American gold medals before turning professional. He sits at No. 2 in the WBA heavyweight rankings, per BoxRec, and is coming off a 10-round decision over Jordan Thompson last November in Orlando.

The winner’s path is tied to Oleksandr Usyk’s schedule. Usyk, who holds the WBA super title along with the IBF and WBO belts, defends the WBC title against former Glory kickboxing champion Rico Verhoeven on May 23 at the Pyramids of Giza in Egypt. Murat Gassiev holds the WBA regular title. A mandatory order from the sanctioning body would follow Usyk’s next fight, putting Saturday’s winner in line for a title shot in late 2026 or early 2027.

Matchroom has billed the promotion “Hair Raiser,” a reference to the January fight in which Miller’s toupee was dislodged by an Ibeh uppercut and became a viral moment well beyond boxing. For more on Miller’s return, see BoxingInsider’s March feature on Miller’s second act.

Undercard

The co-main event is a 10-round lightweight bout between unbeaten Argentinian Alan Chaves and Mexico’s Miguel Madueno. Matchroom signed Chaves to a promotional deal in March and placed him in chief support for his first fight under the banner.

Also on the televised card: welterweight Freudis Rojas Jr. against Damian Sosa, and bantamweight Angel Barrientes against Isaac Rojas Garcia. Light heavyweight prospect Ben Whittaker had been rumored for the card but is instead expected to appear on the Callum Smith vs. David Morrell undercard in Liverpool on April 18.

Broadcast

DAZN’s global coverage begins at 9 p.m. ET / 6 p.m. PT. Main event ringwalks are expected around 11 p.m. ET / 8 p.m. PT, subject to the length of the earlier bouts. The main event is scheduled for 12 rounds.

What’s at Stake

A WBA mandatory position is the immediate prize. For Miller, a win restores a title-picture relevance he has not held since 2019. For Pero, it would be the most significant result of a short professional career and would mark the first Cuban-born challenger at the top of the WBA heavyweight rankings in recent memory.
