Deiveson Figueiredo defends his flyweight championship for the first time as he takes on Alex Perez in the main event of UFC 255 the UFC APEX, Las Vegas, on Saturday night.

The Brazilian phenom has enjoyed a stellar 2020 having twice defeated top contender Joseph Benavidez - and the impressive 32-year-old will be looking to close out the year with a win that could put him in with a shout of winning Fighter of the Year.

However challenger Perez, 6-1 in the UFC, will be no pushover and showed his ferocity during a first round TKO victory over Jussier Formiga last time out.

In the co-main, the dominant women's flyweight champion is aiming for her fourth defence of the 125lb crown as Valentina Shevchenko throws down against Jennifer Maia.
