The Ultimate Fighting Championship welterweight and women's flyweight titles will be on the line as two title fights are now official following the UFC 315 weigh-ins.

The main event will see Belal Muhammad look to cement himself as the best fighter at 170 pounds with a championship defense against Jack Della Maddalena. Meanwhile, the co-main event will see Valentina Shevchenko attempt to defend her second reign as women's flyweight beltholder against Manon Fiorot. All four title tilt participants successfully made weight.

As for the rest of the card, only Bruno Silva failed to make weight, as he was one pound over the middleweight limit for his pairing with Marc-Andre Barriault. Additionally, the Jose Aldo vs. Aiemann Zahabi clash was moved to featherweight on weigh-in day due to weight issues for Aldo. Silva received a 20% fine of his purse, and the match will otherwise proceed as scheduled.

Muhammad (24-3, 1 NC) enters his first title defense on a six-fight winning streak. "Remember the Name" hasn't tasted defeat since 2019 and was dominant in his championship victory over Leon Edwards last year. The 36-year-old weighed 170 pounds on the dot while wearing sunglasses for the pay-per-view headliner.

This marks the biggest fight in the career of Della Maddalena (17-2). The 28-year-old Australian fighter is undefeated inside the UFC, having won seven straight fights. These include a split decision win over Kevin Holland and a brutal knockout of Gilbert Burns in his last outing. "JDM" also weighed 170 pounds exactly for his first championship bout.

UFC 315 main card will air live on ESPN+ pay-per-view at 10 p.m. ET/7 p.m on Saturday. PT. Prelims begin at 6:30 p.m. ET/3:30 p.m. PT on ESPN+ and UFC Fight Pass before moving over to ESPN and ESPN+ at 8 p.m. ET/5 p.m. PT.
