What's at stake at UFC 330?
The UFC welterweight championship in the main-event between champion Makhachev and challenger Machado Garry.
The test for Machado Garry (17-1) could not be more difficult because Makhachev (28-1) is ranked No.1 in ESPN's pound-for-pound list. He is a two-weight world champion who previously ruled at lightweight, and is on a 16-fight win streak. Makhachev has beaten Dan Hooker, Dustin Poirier, Charles Oliveira and Alexander Volkanowski (twice) during his reign of dominance. He won the welterweight title in his first fight at the weight, beating Jack Della Maddalena, last time out so this will be a maiden defence.
Machado Garry could be the second Irish UFC champion after Conor McGregor if he causes an upset.
Dern (16-5) is making the first defence of her strawweight belt against Robertson (17-8).
