Valter Walker has been added to UFC 321 after his planned return at UFC Rio was scratched, keeping his comeback on track with only days’ notice. According to the report, he is now set to face UFC debutant Louie Sutherland on the undercard in Abu Dhabi later this month. The booking matters because it preserves Walker’s return to competition and gives him a new opponent on short notice.
Valter Walker has been rebooked for UFC 321, landing a spot on the Abu Dhabi undercard against UFC debutant Louie Sutherland after his previously scheduled appearance at UFC Rio fell through.
Walker, nicknamed "The Clean Monster," enters the bout riding a strong run of form. The 28-year-old Brazilian trains out of Gor MMA and carries a 15-1-0 professional record into the contest. Standing six-foot-six with a 78-inch reach, Walker is a physically imposing presence, and his statistical profile underlines a grappling-heavy approach — he averages 5.74 takedowns per 15 minutes alongside 2.5 submission attempts per 15 minutes. He also connects at a 52 percent striking accuracy rate, posting around two significant strikes landed per minute.

No verified data for Sutherland was available at the time of this report, though the card marks his promotional debut.
Why it matters
- Walker's original UFC Rio slot was scratched, making this rebooked fight important for maintaining his competitive momentum.
- Sutherland steps into a tough assignment on debut, facing a physically dominant opponent with strong grappling credentials.
- The light heavyweight division continues to develop, and how Walker performs against a fresh face on short notice will offer useful insight into his ceiling at this level.
