Debuting Kevin Vallejos faces a struggling SeungWoo Choi to kick off the UFC Fight Night 254 main card. Will the judges be needed?

Featherweight Kevin Vallejos finally arrived in the octagon at UFC Vegas 104, stopping Swung-Woo Choi in his debut.

Kevin Vallejos is definitely a name to watch after he made a splashy debut with a devastating knocout at UFC Vegas 104. The 23-year-old Contender Series veteran lived up to the hype as he blasted Seung Woo Choi with a huge overhand right that sent the South Korean fighter crashing to the canvas.

After earning a UFC contract through Dana White’s Contender Series, Vallejos (15-1 MMA, 1-0 UFC) made a major first impression when he hurt Choi (11-6 MMA, 4-5 UFC) with a massive punch then swarmed for the TKO at the 3:09. mark of Round 1.
