The UFC 313 fight card lost two fights just hours before the event was set to begin at T-Mobile Arena in Las Vegas.  The heavyweight bout that was scheduled as the featured prelim match between contender Curtis Blaydes and Rizvan Kuniev and the featherweight bout between  John Castaneda and  Chris Gutierrez have been canceled due to illness.  The fight promotion announced that Blaydes and Castaneda fell victim to illness resulting in the two bouts being scrapped from the fight card. It’s unclear whether they matchups will be rebooked for a future event. UFC 313 will proceed with a 10-bout fight card and some adjusting of the bout order
