UFC 328 culminates in a title-fight double-header this weekend, as Khamzat Chimaev and Joshua Van defend their belts in Newark, New Jersey .

In the main event, Chimaev puts the middleweight title on the line for the first time, taking on former champion Sean Strickland after a tense build-up , which spilled over into violence at Thursday’s press conference .

The unbeaten Chimaev is a comfortable favourite here, having dominated Dricus Du Plessis to win the belt in August, after “DDP” twice outpointed Strickland.

And in the co-main event, Van makes his first defence of the flyweight strap, as he defends it against Tatsuro Taira – five months after winning the belt in unique circumstances, when Alexandre Pantoja suffered an injur y early into their fight.
