A pair of unbeaten, rising contenders are set to meet on the undercard of a highly anticipated grudge match.

BoxingScene.com has learned that terms have been finalized for a junior middleweight clash between Jesus Ramos and Joey Spencer. The matchup is the first of three undercard bouts confirmed for the March 25 Showtime Pay-Per-View event from MGM Grand Garden Arena in Las Vegas. The show is headlined by the already announced David Benavidez-Caleb Plant interim WBC super middleweight title fight.

Ramos (19-0, 15KOs) continues his rapid ascension towards title contention, having all but skipped the prospect stage of his young career. The 21-year-old southpaw from Casa Grande, Arizona ranked by all four major sanctioning bodies, though the WBA and IBF still have him in their Top 15 at welterweight.

The only thing that has slowed Ramos’ progress is in-ring activity. The rising contender has not fought since a ten-round decision over Lucas Santamaria last May 28 in Brooklyn, New York. The fight carried a personal motive, Santamaria entered their junior middleweight bout less than four months removed from a questionable points win over Abel Ramos, Jesus’ uncle, last February 5 at Michelob ULTRA Arena in Las Vegas.

Ramos has fought in scheduled ten-rounders for each of his last six contests as he has emerged as a consensus top ten contender.

Spencer (16-0, 10KOs) arrived at that point in his most recent outing. He proved to belong on this level after he earned a convincing decision win over Kevin Salgado in their battle of unbeaten prospects last September 4 at Crypto.com Arena in Los Angeles.

It was a major step up in class for Spencer, who turned pro three months before Ramos in 2018 but whose career has been moved at a less aggressive pace. The 22-year-old Michigan native—who now lives and trains in Union City, California—admittedly grew bored of middling opposition and demanded a challenge. He rose to the occasion and was determined to move forward with his career in lieu of a risk-averse assignment.

Spencer is not ranked in the top 15 by any of the major sanctioning bodies, though a win over Ramos will certainly change that status.

Further details for the March 25 Showtime PPV card are expected to be revealed in the coming days. Benavidez (26-0, 23KOs) and Plant (22-1, 13KOs) are scheduled to participate in a press conference on Thursday in Los Angeles to formally announce and discuss their long-awaited grudge match.
