Dana White Absent from Press Conference

UFC President Dana White did not attend the post-fight press conference, leaving fans with unanswered questions and sparking concern.

One fan`s reaction online was: “Just resign at this point. Clearly wants nothing to do with the UFC anymore.” Another commented: “He doesn’t give a f— about the UFC anymore, it is very obvious.”

Maddalena`s Health Battle Before Title Shot

Jack Della Maddalena overcame a serious health issue potentially threatening his career before reaching the pinnacle of the welterweight division.

His title opportunity came 14 months after breaking his left arm in a victory over Gilbert Burns, requiring surgery. Ten days later, an infection necessitated a second surgery after the wound split. Della Maddalena spent nine days hospitalized on antibiotics.

He continued to face challenges with multiple abscesses forming in the wound over the following five weeks.

Valentina Shevchenko`s Post-Fight Reflections

Following her eighth successful women`s flyweight title defense, Valentina Shevchenko spoke in the Octagon.

She described Fiorot as “a hard opponent, a good striker,” adding that she was “able to do everything I was preparing for the fight.”

On her longevity at the elite level, Shevchenko stated: “I keep going, numbers are nothing to me, it`s about how you feel mentally and physically, this is the most important.”

Vitor Belfort Inducted into UFC Hall of Fame

During the main card broadcast, it was announced that UFC legend Vitor Belfort would be inducted into the UFC Hall of Fame, joining the pioneer wing.

Who is Next for Shevchenko?

Following another dominant performance, speculation turns to Valentina Shevchenko`s next opponent. With her eighth title defense completed, potential fresh challengers are being considered.

Natalia Silva appears to be a frontrunner after her decisive unanimous decision win over former champion Alexa Grasso. Silva is expected to move up the rankings and could pose a new challenge for “The Bullet,” considered by many the flyweight GOAT.

What`s Next for Jack Della Maddalena?

Now holding an 8-0 UFC record, Della Maddalena has quickly ascended to become the undisputed welterweight champion. The 170lbs division is stacked, leading to discussions about his first title defense.

Lightweight champion Islam Makhachev is heavily speculated to be next in line, potentially moving up a division after multiple successful title defenses at lightweight. With Belal Muhammad, his training partner, no longer holding the belt, Makhachev could seek to become a two-division champion.
