Naoya Inoue, the pound‑for‑pound king, enters the ring undefeated at 29 wins, 0 losses, with 26 of those victories coming by knockout. His challenger, San Antonio native Ramon Cardenas, boasts a record of 26 wins and 1 loss, including 14 knockouts, as he steps up for his first shot at an undisputed world title.

The two warriors will clash on Sunday, May 4, 2025, at T‑Mobile Arena in Las Vegas, NV, battling for Inoue’s undisputed junior featherweight world title.

Naoya Inoue, nicknamed “The Monster,” is widely regarded as one of the most fearsome punchers in modern boxing. At just 30 years old, the Japanese superstar boasts a perfect professional record of 29–0, with 26 of those wins coming by way of knockout. Since bursting onto the world stage as a bantamweight prodigy, Inoue has captured world titles in three weight divisions—bantamweight, super‑bantamweight, and now junior featherweight—earning undisputed status in two of them. His combination of explosive power, pinpoint accuracy, and relentless forward pressure has overwhelmed virtually every opponent he’s faced, cementing his reputation as a pound‑for‑pound king.

Standing across the ring will be Ramon Cardenas, a gritty southpaw from San Antonio, Texas, who has slowly but surely carved out his path to this moment. Cardenas enters this contest with a record of 26–1, including 14 knockouts, and holds the interim junior featherweight title after a string of hard‑fought victories. Known for his awkward angles and tight defensive guard, Cardenas has leveraged his length and boxing IQ to outpoint athletic prospects and seasoned contenders alike. His lone defeat came early in his career, but since then he has reeled off 17 consecutive wins, earning respect as a technically sound, resilient challenger who never shies away from adversity.

This championship clash represents a classic matchup of styles—Inoue’s relentless power and ferocity against Cardenas’s unorthodox movement and strategic counter‑punching. For “The Monster,” it’s another opportunity to reinforce his legacy as one of the all‑time greats, defending the undisputed junior featherweight belt he captured last November. For Cardenas, it’s a chance to etch his name alongside boxing’s elite by dethroning an undefeated pound‑for‑pound icon on enemy turf. When they meet at T‑Mobile Arena, fans can expect high‑octane action and a true test of skill, heart, and will on May 4, 2025.

Doors open at 2:45 PM PST, with the main event slated to begin at 3:10 PM PST on fight night.

Tickets start at $156 and can be purchased through the T‑Mobile Arena box office or online at AXS.com.
