Jared Cannonier's Shocking UFC Debut KO & His Journey to Matching Conor McGregor's Milestone (2026)

Imagine stepping into the Octagon for the first time, only to be knocked out before you even find your rhythm. That’s exactly what happened to a former UFC title challenger years before he achieved a milestone shared only with Conor McGregor. But here’s where it gets controversial—was this early stumble a sign of things to come, or just a bump in the road for a fighter destined for greatness? Let’s dive in.

On January 3, 2015, the UFC world witnessed a debut that didn’t go according to plan. Fast forward to 2025, and we’ve seen rising stars like Ateba Gautier—praised by none other than Joe Rogan for his Greek god-like physique—dominate their first years in the UFC. Gautier’s impressive start has fans and analysts alike buzzing about his future. And this is the part most people miss: while some fighters hit the ground running, others face unexpected setbacks that shape their careers in ways they never imagined.

Take, for instance, the fighter who debuted on the same night Jon Jones defeated Daniel Cormier. Despite a rocky start, this athlete has since become a cornerstone of the UFC roster. It’s a reminder that success in the Octagon isn’t always linear. Speaking of milestones, Israel Adesanya recently hinted at a boxing match post-UFC career, but only if the opponent meets his ‘number.’ Who do you think fits the bill? Let us know in the comments!

Now, let’s talk about the UFC’s top newcomers of 2025. Here’s the list that’s sparking debates:

#1 – Quillan Salkilld: 3 wins, 2 finishes, 2 bonuses
#2 – Ateba Gautier: 3 wins, 3 finishes, 2 bonuses
#3 – Kevin Vallejos: 3 wins, 2 finishes, 1 bonus
#4 – David Martinez: 2 wins, 1 finish, 1 bonus
#5 – Malcolm Wellmaker: 2 wins, 1 loss, 2 finishes, 2 bonuses

Now, let’s circle back to that ex-title challenger: Jared Cannonier. Despite losing his undefeated record in a first-round knockout on his UFC debut, Cannonier has proven he’s far from done. His 2025 victory over Gregory Rodrigues showcased his elite-level skills, even as he approaches the twilight of his career. At 41, Cannonier has competed 20 times in the Octagon, though he admits his title aspirations may be fading after falling short against Israel Adesanya.

Here’s a fascinating twist: Cannonier initially joined the UFC as a heavyweight before dropping to light heavyweight and eventually middleweight in 2018. Today, he and Conor McGregor are the only fighters with knockout wins in three different weight classes. But here’s the controversial question: Does this versatility make him a legend, or does his inability to secure a title diminish his legacy? Sound off in the comments!

Cannonier’s debut opponent, Shawn Jordan, shocked the world—especially Derrick Lewis. Fans had mocked Jordan’s physique ahead of UFC 182, but he silenced critics with a hook kick that set up the knockout. Jordan later used the same technique to hurt Lewis in a subsequent fight, becoming the only fighter to beat him twice. Talk about a comeback story!
