The Ring has learned the longtime heavyweight contender will have trainer Derrick "Bozy" Ennis as one of the voices in his corner when facing Lenier Pero at Fontainebleau in Las Vegas on April 25, live on DAZN.

Ennis is the father and trainer of former Ring and unified welterweight world champion Jaron Ennis, while counting recent lightweight title challenger Andy Cruz and highly-rated welterweight contender Jack Catterall among those in his existing stable out of Philadelphia.

This won't be the first time Miller and Ennis have worked together.

Alongside the 37-year-old's longtime trainer Aureliano Sosa, Ennis coached him from the sidelines in August 2024 during his contentious 12-round majority draw against former unified world champion Andy Ruiz. The pairing worked beautifully as Miller (27-1-2, 22 KOs) outworked Ruiz in the second-half of a bruising contest.

Now more than 18 months later, it's all about momentum. Miller picked up his first win in three years when narrowly outpointing Kingsley Ibeh on The Ring 6 undercard at New York's Madison Square Garden on Jan. 31. During his 10-round points win, the brash American had a viral moment when his toupee flew off his head.

Embarrassment aside, which he has since profited from, he's hoping victory over Pero (13-0, 8 KOs) will give his career a belated boost. The hard-hitting Cuban is the WBA's No. 2-rated contender and was last in action winning a competitive 10-round decision against Jordan Thompson, while Miller sits ninth with the same sanctioning body.
