Alice Pereira did not need much space to change the whole fight. After a competitive bantamweight scrap that kept swinging between striking exchanges and wrestling control, Pereira found the opening late in the second round and smashed Hailey Cowan with a straight knee that ended the fight on the spot at UFC Vegas 115.
The finish came at 4:24 of Round 2, and it was the exact kind of shot that makes a prospect jump off the screen. Pereira stayed dangerous even while Cowan was slowing her down with grappling and making her work through awkward stretches. Then the opening showed up, Pereira fired up the middle, and the whole fight was over in an instant.
That matters because this was not one-way traffic before the finish. Cowan had her own moments, especially when she was able to mix in wrestling and keep Pereira from settling too easily into open striking. Pereira still looked dangerous every time the fight had room, and once she got the clean read she needed, she made Cowan pay for it fast.

Pereira got the statement finish she needed after her rough UFC start
This was a big bounce-back moment for Pereira after dropping a split decision in her UFC debut against Montse Rendon. A flat second UFC appearance would have left her in a bad spot early. Instead, she produced the kind of finish that changes the conversation immediately.
Pereira is still only 20 years old, which is the part that jumps out once you step back from the knockout itself. She is young, raw in places, and clearly still developing, but the upside is obvious when she gets a fight into her kind of range. The finishing instinct, the confidence, and the ability to produce something violent under pressure are all there.
After the win, Pereira leaned all the way into that confidence and shouted, “I’m real, motherf*ckers. I’m real! I am so real! Dana, I love money, I love fighting.”
That kind of post-fight moment fits the finish. Pereira did not just win. She gave herself a highlight that people will actually remember. She is now 7-1 as a professional and has her first UFC victory, while Cowan falls to 0-3 in the promotion.
For Pereira, that is the important part. She did not just recover from a disappointing debut. She did it with a finish that put some real heat back on her name.
