- Isaac Lucero, the Mexican junior middleweight prospect known as "La Bestia Jnr," has been active with co-promotional deals and scheduled appearances in the United States as part of his expanding boxing program in 2025–2026. This includes promotional alignment with Sampson Lewkowicz and TM Boxing, aiming to place him on major US cards and potentially world-title pathways.[1][2]

- As of April 2026, multiple boxing outlets list Lucero at 18-0 with 14 KOs, based in Las Vegas, and describe him as a rising 154-pound contender with a focus on advancing to higher-profile opportunities in the welterweight/super welterweight corridor.[3][4][5]
