Dakota Hope replaces Gastón Bolaños, steps in to face Francis Marshall at UFC’s Oct. 31 featherweight event

UFC featherweight contender Francis Marshall will have a new opponent for the promotion’s Oct. 31 event after Gastón Bolaños was forced out with an injury sustained during training. According to reporting from Yahoo Sports on Oct. 8, Bolaños notified the promotion that he suffered a cut on his eyebrow and cannot compete as scheduled.

Bolaños’ withdrawal set up the UFC’s replacement process for a fight that was originally slated for the featherweight division. In the update, the promotion identified Dakota Hope as the new opponent for Marshall, meaning the bout will remain on the Halloween card even though the matchup-updates to the opponent side.

For Marshall, the change is significant mainly for preparation. UFC fights are typically shaped around an opponent’s style, offensive entries, and defensive habits, and a late opponent switch can alter game plans at the most detailed level, from striking patterns to wrestling timing and the specific “threats” each fighter expects to see early in the fight.

For Hope, the opportunity comes with short-term stakes. Replacement fighters often face a heightened timeline, and even when the UFC moves quickly to keep a booking intact, fighters still must adjust quickly to a new opponent. Hope’s entry also ensures that Marshall’s featherweight slot remains contested on a card positioned as a major calendar moment for the promotion’s broader fan base.

The UFC confirmed the replacement as the event approaches, but the report frames Bolaños’ issue as a training injury and does not provide additional medical detail beyond the cut that prevented him from competing. Because official bout paperwork and medical timelines are not included in the reporting summary, the specific severity and medical clearance status are not confirmed here beyond what was described.

What to watch next is whether the matchup provides a clear read on how both fighters adjust. If Marshall’s camp leans into a particular strategic lane based on opponent tendencies, fans may see how quickly Hope’s style translates at the UFC level under replacement circumstances. It will also be worth monitoring any downstream card reshuffling, as late opponent changes sometimes affect weigh-in timing and corner preparations across the event.
