On Tuesday, February 18, Grasso, now the No. 1 contender after losing her title to Valentina Shevchenko at Noche UFC in September 2024, is set for a high-stakes clash with No. 5 Natlia Silva.Grasso, 31, dethroned Shevchenko in March 2023 at UFC 285, defeating the future Hall of Famer via rear-naked choke in the fourth round. The two women fought to a controversial draw in September 2023.LAS VEGAS, NEVADA - SEPTEMBER 16: (R-L) Valentina Shevchenko of Kyrgyzstan punches Alexa Grasso of ...

It now appears Shevchenko is on a collision course with No. 2 contender Manon Fiorot. That fight hasnt been signed, but it seems like the most obvious title fight to make, considering Shevchenko has already fought Grasso three times.Even with a win over Silva, Grasso would likely have more work to do if she hopes to get another shot at the flyweight titleif Shevchenko retains her title after her next fight. If Shevchenko is dethroned, there is a chance Grasso could step right into another title opportunity if she beats Silva.On the other hand, Silva has the chance to ascend into uncharted territory. The 28-year-old has won 12 fights in a row and that includes all six of her UFC bouts.LAS VEGAS, NEVADA - SEPTEMBER 07: (R-L) Natalia Silva of Brazil kicks Jessica Andrade of Brazil in a ...

A victory almost certainly puts her in the top three at 125 pounds and arguably one more win away from securing a title shot.Quite honestly, if she were to beat Grasso impressively enough, she might have an opportunity to put herself in position to be next in line after Fiorot. Theres also the possibility that current strawweight champion Zhang Weili could move up and challenge for the title.Shes fresh off a sparkling performance, easily defending her title against Tatiana Suarez at UFC 312 in Australia. Depending on when Zhang makes her move, youd expect shell get an immediate shot at the 125-pound title.Grasso vs. Silva is likely a main card fight at UFC 315, but its not going to be the main event, and it will almost certainly not be the co-main event. However, it is the most star-studded fight added to the Montreal pay-per-view so far.Alexa Grasso vs. Natlia Silva - Womens FlyweightBrad Katona vs. Bekzat Almakhan - Mens BantamweightHailey Cowan vs. Nora Cornolle - Womens BantamweightMarc-Andr Barriault vs. Bruno Silva - MiddleweightExpect one and perhaps two championship fights to be added to this card over the next 60 days.Whats Next for the UFC?UFC Fight Night Seattle has taken its share of significant strikes over the past two weeks, but its happening, and the card has some intrigue.
