Nick Klein

Overview

Nick Klein's best night in a major promotion came on the Contender Series, not in the UFC: a first-round submission of Heraldo Souza in 37 seconds. The Middleweight from Plymouth, Wisconsin, known as "Blue Collar," is 0-3 in the UFC and carries a three-fight losing streak into his next bout. His overall professional record across all promotions is 6-4.

Three UFC fights, three losses, all inside two rounds. That's the sample so far.

UFC Career

Klein's UFC debut came in February 2025 against Mansur Abdul-Malik at UFC Fight Night: Cejudo vs Song. It ended by KO/TKO in the second round at 3:24. In August 2025 he met Andrey Pulyaev at UFC Fight Night: Taira vs Park and lost the same way, KO/TKO in round two, this time at 1:31.

The third loss, in October 2026, broke the pattern only in method. Joe Kropschot submitted him at 1:25 of the second round at UFC Fight Night: Moicano vs Nolan.

Every UFC fight has ended in round two. That's a small sample, but it's a consistent one.

Fighting Style

Klein is a grappler first. He shoots for takedowns often and hunts for submissions, and he does both far more than most UFC fighters. His takedown defense is about average.

His striking is the weaker side of his game. He lands less often than most fighters and gets hit easily, though he is accurate when he does throw.

His UFC record is 0-3. Two of the losses came by KO/TKO and one by submission, so he has not yet gone the distance in the Octagon.
