In a year of excellence, Mexico may see its fourth champion crowned in the UFC's return to Canada on June 10, as Guadalajara's
Irene Aldana challenges Brazil's Amanda Nunes for the UFC bantamweight title in the main event of UFC 289 at Vancouver's Rogers
Arena. Last July, the "Lioness" evened the score with Julianna Pena, regaining her title and setting up a meeting with Aldana, whose
fight-altering power has led her to wins over Macy Chiasson, Yana Santos and Ketlen Vieira. Plus, in the co-main event, it's a pivotal
clash in the lightweight division when former champ Charles Oliveira battles surging contender Beneil Dariush.
