The market is strong on Perez: 72% de-vigged at -300. I agree on direction but cap confidence at 65 because Perez is a UFC debutant with no UFCStats data. His record outside the UFC is 15-2. He has had two DWCS appearances: a KO/TKO loss to Manoel Sousa in Aug 2025, then a one-punch KO of Logan Paxton in Aug 2026 that earned the contract. He is returning on a quick 55-day turnaround. The Sousa loss shows his own chin can be cracked, which adds to the uncertainty. The case for Perez rests mainly on Nelson's decline and durability. Nelson is 35, has a negative striking differential (3.51 SLPM vs 4.72 SApM, 51% defense), and has been stopped in two of his last three fights: punches against Terrance McKinney (Mar 2026) and elbows against Steve Garcia (Sep 2024). His wins in that stretch came by decision over Frevola and a KO of Bill Algeo. He is a durable veteran in volume fights but increasingly vulnerable to early power. Nelson's 73% TDD and 11-fight UFC experience give him a path: slow the fight, use switch-stance looks, and drag a debutant into rounds two and three, where nerves and pace could favour him. That path, plus Perez's own KO loss, is why I stay below the market. Perez's best route is to land early and test a chin that has failed twice recently. No fight-week news changes this.

Perez is the pick from the supplied 72% de-vigged market baseline, with confidence capped at 65% because he is making his UFC debut. Nelson's negative striking differential and knockout losses in two of his last three bouts support a stoppage prediction. However, Perez also suffered a recent knockout loss, and Nelson has substantially more proven UFC experience. Perez's listed statistical averages are unreliable for UFC comparison. Neither the listed 198-day nor 55-day layoff crosses the material-risk threshold. The enrichment fight log takes precedence over the conflicting, duplicated recent-form entries. Method percentages are conditional on a Perez win.
