The championship bouts scheduled for UFC 328 on Sunday, May 10 (Philippine time) are officially locked in after all four world title fight participants successfully made weight during the official weigh-ins.

Set to take place at the Prudential Center in Newark, New Jersey, the event will be headlined by UFC middleweight champion Khamzat Chimaev defending his crown against former titleholder Sean Strickland.

Both competitors tipped the scales at the championship limit of 185 pounds.

The contest serves as Chimaev’s first defense of the belt he captured by dethroning Dricus du Plessis in August 2025.

The unbeaten standout carries a perfect 15-0 record into the Octagon and continues to fulfill expectations that surrounded him from the start of his UFC journey.

“Borz” rapidly emerged as one of mixed martial arts’ brightest stars after dismantling three opponents within two months while absorbing only one significant strike across his first four appearances.

He later added victories over former champions Kamaru Usman and Robert Whittaker before claiming the divisional top prize.

Standing opposite him is Strickland, who enters with a 30-7 slate following a knockout win over Anthony Hernandez earlier this year.

The outspoken American previously stunned the sport by defeating Israel Adesanya in 2023 to capture middleweight gold.

Meanwhile, flyweight king Joshua Van and challenger Tatsuro Taira both weighed in at 125 pounds for their co-main event showdown.

The matchup marks the first time two male fighters of Asian descent will compete for a UFC world title.

Representing Myanmar, Van owns a 16-2 record with 10 stoppage victories. “

“The Fearless” claimed the 125-pound championship in December last year after Alexandre Pantoja was unable to continue due to an arm injury suffered during a first-round takedown exchange.

Taira, meanwhile, enters with an 18-1 mark and momentum from a victory over former champion Brandon Moreno.

Both athletes were born in the 2000s, adding further significance to a bout viewed as a changing of the guard in the division.
