Looking back at the new hires at heavyweights, both on the main UFC roster and the Contender Series, one name that people in our comments kept asking about was “The Hammer” RJ Harris. Strong off two finishes in front of regional MMA enthusiasts on the LFA stage, Harris was viewed as a shoo-in for the UFC sooner rather than later. With Allen Frye Jr. ditching out of his UFC Oklahoma City bout against Alvin Hines, Mick Maynard and the UFC brass decided it was time to sign the Ohio giant.
Harris is an undefeated prospect from Zanesville, Ohio, representing Sprawlin & Brawlin MMA. After a successful amateur career that saw him capture the Caged Thunder amateur heavyweight title, Harris made his professional debut in 2025. Shortly after, he quickly built a 5-0 record in less than a year. His early performances with the Ohio Combat League and Caged Thunder earned him a spot in the LFA. There, he has a win over Phillip Latu at LFA 231 helped put his name on the radar. Shortly after, Harris, who was in camp for a matchup at LFA 237, received his call and became the newest heavyweight addition to the promotion. At 27, “The Hammer” enters the UFC as one of the youngest in the division, looking to make his mark in the big leagues.
Harris is one of those prospects who somehow manages to be both intriguing and frustrating at the same time. Standing 6’6″ with an 80-inch reach, he has the kind of frame that immediately catches your attention in the heavyweight division. His undefeated record also comes against a respectable level of competition for a young heavyweight, which is more than can be said for many prospects who spend their early careers flattening obvious cans. Without looking at the tape, there are no obvious red flags concerning RJ. But when you actually watch him, things go downhill… quick.
Physically, Harris is tough, durable, and owns a solid chin. He’s comfortable fighting at his own pace, feints well, and generally prefers to counter rather than lead the dance. While he isn’t a particularly skilled grappler, he’s quick to capitalize when opponents make mistakes, especially with guillotines and other front headlock attacks. He also isn’t afraid to spend time controlling opponents against the fence or from top position if it means banking rounds.
The problem is that there’s a reason he ends up needing that durability. Harris gets hit… a lot. His defense can only be described as “tall guy defense,” where keeping your head six inches higher than everyone else’s apparently counts as head movement. He often blitzes forward with his chin in the air, retreats in straight lines, barely checks kicks, and leaves both his body and head open far too often. Technically, his boxing is rough around the edges; he rarely strings combinations together, and his striking lacks variety. He’s also slow, flat-footed, and not particularly athletic, making striking exchanges a losing proposition more often than not.
His grappling isn’t without flaws either. He frequently jumps on standing guillotines that simply aren’t there. While his chokes are dangerous, his long frame can actually work against him when trying to apply finishing pressure. He’s basically too tall and would need to be on his toes to get the tap. Wrestling is almost an afterthought for Harris, with most of his takedowns coming from strength-based trips rather than technique. His clinch game is largely limited to pressing opponents against the cage with the occasional knee.
In many ways, Harris feels like a fighter who’s simply “okay” everywhere without truly excelling anywhere. The encouraging part is that he’s still young, and heavyweight is a division where late development isn’t uncommon. If he can clean up some of the glaring defensive issues and make better use of his physical tools, there’s something to build on. Right now, though, his biggest asset may simply be the fact that he has plenty of time to figure it all out.
RJ draws Alvin Hines in his UFC debut. This has all the makings of an ugly heavyweight fight, but ugly doesn’t necessarily mean boring. Neither man is particularly clean on the feet, and both have defensive issues that should create plenty of chaotic moments. Harris has a habit of making fights messy, leaning on his size, durability, and opportunistic submission game whenever exchanges start breaking down. Against someone like Hines, who has struggled defensively and doesn’t offer much one-shot power, that style could pay off. Hines is tough enough to survive bad spots, but Harris has shown he’s willing to keep pushing until something opens up.
Hines is also returning from a lengthy layoff following a suspension, adding another layer of uncertainty to the matchup. I’ll side with Harris to pull off the upset in his debut, but this feels as close to a true 50/50 fight as you’ll find on the card.
