Profile
Overview
28 seconds for the win, 21 seconds into round two for the loss. JooSang Yoo, "Zombie Jr." out of Korean Zombie MMA, has fought three times in the UFC at featherweight, and the early part of those fights has decided most of it. His UFC record is 1-2, inside a 9-2 professional record across all promotions.
He's still looking for his second UFC win.
UFC Career
Yoo debuted at UFC 316 and beat Jeka Saragih by KO/TKO in round 1, 0:28. That is his only UFC win and his only first-round finish.
Four months later, at UFC 320, Daniel Santos stopped him by KO/TKO at 0:21 of round two. At UFC 331 he went the distance with Michael Aswell Jr. and lost a split decision after three rounds.
He carries a two-fight losing streak into his next bout. Three fights is a small sample.
Fighting Style
His career numbers say he lands more strikes per minute than the UFC average, but he also absorbs more than most. Accuracy and defense sit around average. This is a striker, not a grappler: he rarely shoots for takedowns or hunts submissions. But he is hard to take down, and that is the strongest number in his profile.
Notable Wins
- Jeka Saragih — KO/TKO, round 1 (0:28), UFC 316 (2025)
