If you had asked anyone in the wrestling bubble three years ago if Jeff Cobb was headed to Stamford, they probably would’ve laughed. He was the quintessential "indie" guy who outgrew the indies, a powerhouse built like a refrigerator who could somehow do a standing shooting star press without breaking a sweat. For years, the narrative was that Cobb was too "pro-wrestling" for the WWE machine. He was the guy who prioritized the G1 Climax over a steady paycheck and a travel schedule through the Midwest.
Then 2025 happened.
Honestly, the wrestling world shifted on its axis when Cobb finally made the leap. It wasn't just a signing; it was a statement. After years of "will they, won't they," the man who once famously said he turned down WWE because money wasn't everything finally walked through the curtain. But it wasn't as the Jeff Cobb we knew from New Japan Pro Wrestling (NJPW) or Lucha Underground.
The Backlash Debut That Changed Everything
The scene was WWE Backlash 2025. LA Knight was essentially in a two-on-one fight against the remnants of Solo Sikoa’s Bloodline, trying to claw the United States Championship away from Jacob Fatu. Just as Knight seemed to have a path to victory, this absolute unit of a man emerged from the crowd.
He didn't just interfere. He dismantled.
Michael Cole, in his usual high-octane fashion, dubbed him "one of the biggest free agents on the planet." It was a surreal moment for fans who spent the last decade watching him as Matanza Cueto or as the muscle of United Empire. Seeing him toss a main-roster star like LA Knight against a ring post like a sack of laundry was the "welcome to the big leagues" moment everyone had been waiting for.
Shortly after, the name change happened. Say goodbye to Jeff Cobb, and hello to JC Mateo.

WWE names are always a point of contention, right? Fans groaned. They always do. But the rebranding served a specific purpose: fitting him into the new era of The Bloodline. Despite not being Samoan—he’s of Filipino descent and was born in Honolulu—the storyline logic was that Solo Sikoa needed an enforcer he could actually control. Jacob Fatu is a "Werewolf," a chaotic force of nature. Solo needed a mercenary. He needed JC Mateo.
Why It Took Over a Decade to Happen
It’s easy to forget that Cobb actually had a WWE tryout way back in 2014.
He’s talked about this in interviews, specifically how he looked at a clipboard during the check-in and saw two columns: "Athletes" and "Indie Workers." Despite being an actual Olympian who represented Guam in the 2004 Summer Games, WWE’s scouts at the time stuck him in the "Indie" column. That kind of tells you everything you need to know about the old regime's mindset.
Cobb didn’t get an offer then. Looking back, he’s been pretty candid that if they had offered him something in 2014, he would’ve taken it in a heartbeat. Instead, he went on one of the most incredible runs in modern history:
- Lucha Underground: He became the terrifying, masked Matanza Cueto. He was booked like an unbeatable god, which is hard to do when you’re 5’10”, but Cobb is so wide and powerful that he looked like a giant on screen.
- New Japan Pro Wrestling: This is where he truly polished his craft. As a member of the United Empire, he won the IWGP Tag Team titles three times and held the NEVER Openweight Championship.
- AEW & ROH: He floated through various promotions, proving he could work any style with anyone.
When WWE came knocking again in 2020, he actually said no. He wanted creative freedom. He wanted the Japan life. It took another five years and a massive shift in WWE's internal culture (thanks to the Triple H era) to finally get the "Imperial Unit" to sign on the dotted line.
The Contract: How Long Is He Staying?
For those worried this is a short-term cameo, think again. Recent reports from Fightful and other insiders have confirmed that JC Mateo signed a three-year deal that keeps him locked into WWE through the spring of 2028.

This wasn't a "let's see if this works" arrangement. WWE cleared out a significant spot for him by having him leave NJPW while he was still one-half of the IWGP Tag Team Champions. That caused a huge stir in Japan. NJPW had to vacate the titles, and Cobb’s final match was a bittersweet loss to the legendary Hiroshi Tanahashi on April 19, 2025.
By the time he showed up on SmackDown, he was ready for the grind. He’s currently a cornerstone of Solo Sikoa’s "MFT" group. The dynamic is fascinating because while Tama Tonga and Tonga Loa bring the family legacy, Mateo brings the raw, "outsider" power that makes the faction feel more like a dangerous mercenary squad than just a family feud.
Recent Rivalries and the Wyatt Sicks
As we move through 2026, Mateo has been pulled into one of the most chaotic storylines on Friday nights. The MFTs have been clashing with The Wyatt Sicks.
If you caught the recent episode of SmackDown, things got ugly fast. We’re talking a full-blown ringside brawl where the referees completely lost control. The visual of Mateo standing toe-to-toe with Erik Rowan was a "big man" lover's dream. These two threw heavy shots until Rowan managed to clear the ring, but the seeds were sown for a massive collision later this year.
What Most People Get Wrong About Him
The biggest misconception? That he's "too old" or "too small."
Yes, Jeff is in his 40s. But in the modern landscape, "40 is the new 30" for power wrestlers who know how to protect their bodies. His style isn't about taking crazy bumps; it's about making the other guy take them. He uses a "Tour of the Islands" powerslam that looks like it could legitimately break a human being in half.

And the height thing? Sure, he's 5'10". In the 1980s, that would’ve been a death sentence in WWE. Today? He’s the same height as many of the top stars, but he weighs nearly 300 pounds of pure muscle. He doesn't look small; he looks like a boulder.
What’s Next for JC Mateo?
The immediate future is all about the Bloodline Civil War. With Roman Reigns and Solo Sikoa constantly at odds over the "Ula Fala" (the ceremonial lei), Mateo is the ultimate X-factor.
There's a strong chance we see a massive "Bloodline Rules" match at a major Premium Live Event where Mateo's amateur wrestling background becomes the deciding factor. While everyone else is throwing superkicks, he's the one who can actually take people down and keep them there.
Actionable Insights for Fans:
- Watch the Old Tape: If you only know him as JC Mateo, go find his Matanza Cueto matches from Lucha Underground Season 2. It's some of the best "monster" booking in the last twenty years.
- Follow the SmackDown Power Rankings: Keep an eye on how WWE protects him. He rarely loses clean, which suggests they are grooming him for a massive singles run once the Bloodline story eventually cools off.
- Monitor the NJPW Connection: With WWE and NJPW's relationship thawing slightly over the years, don't be surprised if we see a "Forbidden Door" style moment where Mateo returns to Japan for a one-off show while still under WWE contract.
The move from Jeff Cobb to JC Mateo wasn't just a name change; it was the final evolution of a world-class athlete who finally found his way to the biggest stage in the world. He’s proof that if you’re good enough, the machine will eventually come to you.
Next Steps for Your Wrestling Knowledge:
You should look into the history of the United Empire in NJPW to see how Cobb developed his current "Enforcer" persona. It provides a ton of context for why he fits so perfectly into Solo Sikoa’s current vision for the Bloodline. Also, keep tabs on the upcoming SmackDown tapings; the tension between Mateo and Jacob Fatu is being teased heavily, and that explosion is going to be must-see TV.
