The news
Arnold Allen offered a candid self-assessment of his unanimous-decision win over Melquizael Costa in the UFC Vegas 117 main event, telling reporters the performance was "alright" but limited by illness. "I think I could have pushed a bit more, but I was concerned about how hard I could push while being sick," Allen said. "I really didn't want to let it" slip away, the English featherweight added.
Prior context
The May 16 victory snapped a recent skid for Allen, who controlled the action through the final bell of a scrappy five-round contest in Las Vegas. Judges turned in a one-sided card, with Cageside Press reporting a 50-45, 50-45 official result in Allen's favor. Allen has also credited Costa's striking, telling the post-fight press conference that the Brazilian's first back kick "felt like a battering ram in the stomach."
Key takeaways
- Result: Allen def. Costa by unanimous decision (50-45, 50-45) at UFC Vegas 117 main event
- Allen fought through illness during fight week, by his own admission
- Win snaps a recent losing skid in the UFC featherweight division
- Allen singled out Costa's back kick as the fight's most punishing weapon
What it means
For Allen, the win is a critical stabilizer at 145 pounds after a stretch of professional setbacks that had dented his standing as a top featherweight contender. Headlining a Fight Night and going the full 25 minutes against a dangerous striker — even at reduced output — re-establishes him in the divisional title picture. The illness disclosure also reframes the performance: a measured, energy-conserving game plan rather than a sign of diminished tools.
What to watch next
Allen's next booking will reveal how the UFC values the win, with a ranked featherweight matchup the logical next step if he comes through the post-fight medical window cleanly. Whether he uses the time to fully recover or pushes for a quick turnaround will shape his 2026 trajectory.
