## Background
The main event matched two fighters at turning points in the welterweight division. Della Maddalena had won the 170-pound title by beating [Belal Muhammad](https://www.edgepedia.org/belal-muhammad) via unanimous decision at UFC 315 in May 2025, extending an 18-fight winning streak, then lost the belt in his first defense to [Islam Makhachev](https://www.edgepedia.org/islam-makhachev) by unanimous decision in the main event of [UFC 322](https://www.edgepedia.org/ufc-322) at Madison Square Garden in November 2025, a fight in which he spent long stretches pinned to the mat.[8](https://apnews.com/article/edaf06af910ca9bdfaf83b3fdee06aa3) • [6](https://www.mmafighting.com/ufc/485292/ufc-perth-predictions) The Perth card was his first fight since losing the title and his second in his home country, and his first in Australia since February 2023.[7](https://www.cbssports.com/mma/news/ufc-fight-night-odds-lines-australia-fight-card-predictions-start-time-della-maddalena-prates-picks/)
**Prates entered on a surge.** The Brazilian, who trains with [Fighting Nerds](https://www.edgepedia.org/fighting-nerds) and Vale Top Team, was ranked fifth at welterweight and had beaten [Leon Edwards](https://www.edgepedia.org/leon-edwards) by knockout in his previous bout at UFC 322, having won six of seven UFC fights with a [Performance](https://www.edgepedia.org/performance) of the Night bonus in each of those victories.[3](https://www.sherdog.com/news/articles/Why-Carlos-Prates-beats-Jack-Della-Maddalena-at-UFC-Perth-201018) • [6](https://www.mmafighting.com/ufc/485292/ufc-perth-predictions) • [7](https://www.cbssports.com/mma/news/ufc-fight-night-odds-lines-australia-fight-card-predictions-start-time-della-maddalena-prates-picks/) He said before the fight that a win over the former champion would move him close to a title opportunity, and that he had traveled to Perth two weeks early to adapt.[9](https://as.com/masdeporte/polideportivo/prates-makhachev-es-el-numero-uno-pero-puedo-noquearle-f202605-n/) Despite the difference in momentum, bookmakers made the fight nearly even, with both men at -110.[7](https://www.cbssports.com/mma/news/ufc-fight-night-odds-lines-australia-fight-card-predictions-start-time-della-maddalena-prates-picks/)
## The fight and result
Prates won the main event by knockout, according to the UFC's Brazilian-language results coverage, which headlined its report with the stoppage of Della Maddalena.[4](https://www.ufc.com.br/news/card-completo-resultados-ufc-perth-2026) The UFC's official bonus-coverage photo caption for the event shows Prates landing a knee on Della Maddalena during their welterweight fight at RAC Arena.[10](https://www.ufc.com/news/bonus-coverage-ufc-perth-prates-della-maddalena) The result ended Della Maddalena's bid to rebuild immediately after the Makhachev loss and strengthened Prates's case for a 170-pound title shot.[6](https://www.mmafighting.com/ufc/485292/ufc-perth-predictions)
