UFC 331: How to Watch and Full Fight Card

In the main event, flyweight kingpin Joshua Van seeks to defend his strap for a second time when he faces the man he originally dethroned for the belt, Alexandre Pantoja. In the penultimate bout of the evening, number one lightweight contender Arman Tsarukyan trades blows with Brazilian standout Maurício Ruffy.  

UFC 331 Main Event

Putting his crown on the line earlier this year against Tatsuro Taira at UFC 328, Van wowed audiences by handing the dominant Japanese grappler his first ever defeat, finishing the Okinawa native in the five round. With a second victory over the man he trounced to gain the championship, “Fearless” will undoubtedly cement his place as the true ruler of the 125-lb division.

Holding several promotional records like most finishes and wins in the flyweight division’s history, Pantoja was once hailed as a pound-for-pound great after a four title defense run as champion. Eager to settle the score against his nemesis, “The Cannibal” has his eyes dead set on getting back his place at the head of the pack.

UFC 331 Co-Main Event

In the midst of a five-fight winning streak, Tsarukyan has established himself as the clear next best man at 155-lb after several key triumphs over the likes of Beneil Dariush, Dan Hooker, and Charles Oliveira. For the surging “Batman,” a win at UFC 331 can mean a potentially massive confrontation with current divisional apex Justin Gaethje.

Following a disastrous setback to Benoît Saint Denis back in 2025, Ruffy has since relocated to featherweight champion Alexander Volkanovski’s gym in Australia. The switch has paid off in spades for the 30-year old, with him winning his last two contests in a row, stopping both Rafael Fiziev and Michael Chandler.
