The main event will see the undisputed UFC welterweight title put on the line as newly-crowned champion Belal Muhammad takes on Australian contender Jack Della Maddalena for the 170-pound crown, while the co-main event will feature a battle for the undisputed women’s flyweight championship as champion Valentina Shevchenko faces off against surging French contender Manon Fiorot.
All four championship fighters successfully made weight for their respective matchups, with Muhammad and Della Maddalena both hitting 170 pounds, while Shevchenko tipped the scale for her flyweight bout at 124 pounds, while Fiorot hit championship weight on the nose, hitting 125 pounds exactly.
The fight card also features an array of Canadian fighting talent, including Aiemann Zahabi, who takes on UFC royalty in the form of former featherweight champion Jose Aldo in a main card bout, which was originally set as a bantamweight contest. But, after discussions backstage after what appeared to be a rough weight cut for Aldo, the bout was redesignated as a featherweight matchup, with Aldo and Zahabi coming in at 143 and 142 pounds, respectively.
Also flying the flag for Canada are short-notice prospect Kyle Prepolec, who takes on Benoit Saint Denis, Mike Malott, who stars in the featured preliminary card bout against Charles Radtke, and Jasmine Jasudavicius, who will look to move towards title contention at flyweight when she takes on former strawweight champion Jessica Andrade.
There’s also a pivotal contender clash in the women’s flyweight division, as former champion Alexa Grasso and in-form Brazilian contender Natalia Silva face off knowing that a big win could secure the next shot at the 125-pound title. They all successfully made weight for their respective bouts, with just one fighter missing weight. Middleweight Bruno Silva missed weight by one pound and will forfeit 20 percent of his fight purse to his opponent Marc-Andre Barriault. Their fight will proceed, as scheduled.
The UFC 315 Weigh-In Show was hosted by Dan Hellie, with Din Thomas joining Weigh-In Show regulars Laura Sanko and Daniel Cormier as they looked ahead to fight night, broke down all the major matchups, and chatted to the fighters after they had stepped off the scale.
