UFC welterweight champion Belal Muhammad and Jack Della Maddalena made weight Friday before they square off in the UFC 315 main event Saturday in Montreal.

Muhammad and Della Maddalena both weighed in at 170 pounds.

Ian Machado Garry weighed in as a backup for the main event, hitting 168 pounds.

Women's flyweight champ Valentina Shevchenko and Manon Fiorot were also on the mark for the co-main event. Shevchenko came in at 124 pounds, and Fiorot tipped the scale at 125.

Additionally, the UFC announced midway through the weigh-in session that the bantamweight fight between Jose Aldo and Aiemann Zahabi had moved to featherweight. The promotion made the change earlier Friday when it became clear Aldo wouldn't make weight, according to Uncrowned's Ariel Helwani.
