Valter Walker’s foot fracture opened the door for Tyrell Fortune — a former Bellator heavyweight with a 17-3 record and no UFC experience — to make his promotional debut against the #8-ranked Marcin Tybura. At 40 years old, Tybura is the most durable heavyweight on the UFC roster and arrives off a mixed 2025 that included a win over Mick Parkin and a first-round KO loss to Ante Delija. Fortune is the definition of short-notice opportunity.
Fighter Breakdown
- 27-10 overall, 14-9 UFC — one of the most experienced heavyweights in UFC history with a Master’s degree from the University of Lodz before fighting became his career
- Four Performance of the Night bonuses in the UFC — devastating finishes of Viktor Pesta, Greg Hardy, Walt Harris, and Tai Tuivasa on his record
- Beat Mick Parkin by decision in March 2025 — showed he can still compete effectively at 265 pounds even in his 40th year
- KO loss to Ante Delija in R1 at UFC Fight Night 258 (September 2025) — the chin has been compromised at heavyweight pace
- Concern: 40 years old — any heavyweight fight carries one-punch KO risk, and Fortune’s wrestling base from a Bellator career creates grappling uncertainty.
- 17-3 overall — spent the majority of his career in Bellator (13-2 record) before wins in PFL and smaller promotions in 2025 earned this UFC contract
- Former wrestler stepping up to the sport’s biggest stage — his grappling-first approach could create problems for Tybura if he establishes takedowns early
- Won three consecutive fights in 2025 against regional opposition — arrived in form and motivated for the biggest opportunity of his career
- Concern: This is a significant step up in competition — Tybura has 14 UFC wins and a career built on beating exactly the type of fighter Fortune represents. The experience gap is enormous.
Tybura wins this comfortably. The step up from Bellator/regional competition to a top-10 UFC heavyweight on short notice is one of the largest quality gaps on this entire card. Tybura’s experience, grappling credentials from his M-1 championship era, and measured heavyweight striking should be more than enough against a UFC debutant stepping in short-notice. Fortune’s wrestling is the one genuine threat — if he takes this to the mat early and sustains it, the fight becomes less predictable. But Tybura’s UFC-level grappling defense, built over 23 UFC appearances, should handle what Fortune offers.
