Stewart Nicoll at UFC Vegas 115: what changes by Saturday night
Stewart Nicoll enters UFC Vegas 115 with a clear mandate: turn promise into a first Octagon victory. The flyweight matchup with Alessandro Costa is shaped by recent losses on both sides, but the stakes are sharper for Nicoll because his UFC run has not yet produced a win.
What Happens When the Pressure Fights the Power?
The current picture is straightforward. Costa is 14-5 and comes in after a TKO loss to Alden Coria, following a second-round knockout win over Kevin Borjas. Nicoll is 8-2 and is still searching for his first UFC victory after a unanimous decision loss to Lucas Rocha and a quick submission loss to Jesus Aguilar. Both fighters need a reset, but they arrive there through different paths.
The betting lines place Costa as the favorite, with Nicoll listed as the underdog. That pricing reflects the broader read on the matchup: Costa’s striking threat and takedown defense are viewed as the key stabilizers, while Nicoll’s best route is a wrestling-heavy approach that can slow the pace and change the rhythm of the fight.
What If the Fight Stays on the Feet?
If the fight becomes a kickboxing exchange, Costa appears positioned to control the more favorable terms. He is described as having blistering hand speed, severe knockout power, and an advantage in striking volume and accuracy. His takedown defense is also presented as a major barrier for Nicoll’s level changes.
Nicoll’s challenge is that his style depends on getting the fight to the mat and building top pressure. If those entries are repeatedly stuffed, he may be forced into longer striking sequences against a fighter who is comfortable trading and countering. Costa’s experience and sharper offensive pace are the reasons he is widely framed as the more likely winner if the bout remains upright.
What If Nicoll Can Force the Grappling?
Nicoll’s best path is equally clear. He needs to crowd Costa, force backward movement, and disguise his takedowns behind pressure. Once the fight hits the canvas, his top control and heavy hips could drain Costa’s energy and limit the Brazilian’s explosive output.
That path is not automatic. Costa is described as a high-level black belt who can scramble, sweep, or recover if the fight turns messy on the ground. Still, Nicoll does not need a perfect wrestling performance to matter; he only needs enough sustained control to keep Costa from settling into his preferred striking rhythm.
| Scenario | Key edge | Likely outcome |
|---|---|---|
| Best case for Costa | Clean striking, strong takedown defense | Late finish or clear decision |
| Most likely | Mixed phases with Costa’s pace showing through | Costa edges the action |
| Most challenging for Costa | Nicoll secures takedowns and top control | Nicoll grinds out a win |
Who Wins, Who Loses, and Why Does It Matter?
The clearest winner if Costa imposes his rhythm is the fighter who already has the stronger standing profile. Costa would add a needed rebound and validate the market’s confidence in his ability to neutralize wrestling and punish mistakes. The biggest loser in that version is Nicoll, whose UFC storyline would remain stuck at zero wins despite clear wrestling-based ambition.
If Nicoll gets his way, the outcome matters for a different reason: it would show that his pressure game can survive against a dangerous and more experienced opponent. That would change how his future bouts are priced and discussed. For Costa, a loss would deepen the sense that recent volatility is still unresolved.
There is one honest limit here: the matchup has enough contrast that momentum can swing on one successful takedown sequence or one clean counter. That uncertainty is what makes the fight interesting, but it also means a narrow edge is more realistic than a broad one.
What Should Readers Take Into Saturday Night?
The most useful way to read Stewart Nicoll is through the style clash, not through hype. If he can convert pressure into takedowns and keep Costa working underneath him, he has a route to an upset. If Costa keeps the fight upright and forces Nicoll to reset repeatedly, his sharper striking and defensive wrestling should carry the night.
For readers, the key is to watch the early grappling exchanges and the first time Nicoll has to enter from distance. That may tell the story before the scorecards ever matter. Stewart Nicoll is the name to watch, but the fight still hinges on whether he can make his preferred game real under UFC Vegas 115 pressure.
