Yi Sak Lee vs Luis Dias de Assis Prediction

FIGHT WINNER

Luis Dias de Assis

Predicted: Submission, Round 2

59%

Luis Dias de Assis (16-5-0) enters this bout with significantly more professional experience than Yi Sak Lee (8-1-0), and recently earned his UFC contract with a second-round submission victory on Dana White's Contender Series in October 2025. Dias is a formidable grappler with excellent jiu-jitsu, boasting 8 submission wins out of his 16 victories. While Yi Sak Lee is described as a fast starter with a well-rounded skillset, his UFC debut against a seasoned finisher like Dias presents a tough challenge. Dias's average fight time of 9:37 suggests he often finishes fights before the final round, aligning with his submission prowess. Although Dias showed some hesitancy to strike in his Contender Series bout, his ability to secure a submission against a tough opponent demonstrates his primary threat.

SPREAD PREDICTION

Luis Dias de Assis -1.5 Rounds (-1.5)

59%

Luis Dias de Assis is a proven finisher with 8 TKO/KO and 8 submission victories, making up the majority of his wins. His recent Contender Series win was a submission in the second round. Given his grappling background and ability to find finishes, picking him to win within the first two rounds (covering a -1.5 round handicap) is a plausible outcome, as he often looks for the finish rather than going the distance.

TOTAL PREDICTION

Under 2.5

59%

Luis Dias de Assis has an average fight time of 9 minutes and 37 seconds, indicating that his fights frequently do not go the full three rounds. With both fighters showing a propensity for finishes (Lee with 4 KO/TKOs and 3 submissions, Dias with 8 KO/TKOs and 8 submissions), an early stoppage by either fighter is a strong possibility. Therefore, betting the 'under' 2.5 rounds is a confident pick, expecting a finish before the midway point of the third round.
