Carlos Ulberg Sets UFC Record With Lightning-Fast KO

New Zealand light heavyweight Carlos Ulberg made UFC history Saturday night with the fastest knockout in the division’s history, stopping opponent Tyson Pedro in just 12 seconds at UFC Fight Night in Las Vegas. The stunning victory marks Ulberg’s sixth straight win and propels him into title contention.

The record-breaking finish came immediately after the opening bell when Ulberg landed a crushing right hand that sent Pedro crashing to the canvas. Referee Herb Dean waved off the fight without a count, confirming the quickest KO ever in the UFC’s 205-pound division.

Ulberg’s viral moment is trending across US sports platforms as fans debate whether the 33-year-old striker deserves a top-5 ranking. ESPN analysts noted the knockout surpassed the previous light heavyweight record of 15 seconds set by Ryan Jimmo in 2012.

The City Kickboxing product told reporters post-fight, "I visualized this exact scenario all week. When I saw him drop, I knew we made history." Pedro, who suffered his first knockout loss since 2018, was medically cleared after the event.

UFC President Dana White called the finish "one of the most devastating I’ve seen" during the ESPN+ broadcast. The promotion shared Ulberg’s highlight across social media, where it amassed over 2 million views within three hours.

With this victory, Ulberg improves to 9-1 overall and 6-1 in the UFC. MMA experts suggest he could face former title challenger Anthony Smith or rising star Azamat Murzakanov in his next bout. The UFC has yet to announce Ulberg’s next matchup.

The record-setting performance comes at a pivotal time for the light heavyweight division, where champion Alex Pereira recently vacated the belt. Ulberg’s highlight-reel finish positions him as a fresh contender in the reshuffling 205-pound landscape.
