The time of the fight is another hurdle for Mark Hunt ahead of his interim heavyweight title shot at UFC 180 in Mexico City this weekend.
Hunt's five-round bout with Brazilian Fabricio Werdum (18-5-1) isn't scheduled to begin until 11pm local time on Saturday night (6pm, Sunday NZT), which will be the latest time of the day Hunt has ever fought.
The 40-year-old has 64 professional fights to his name across boxing, kickboxing and MMA but even in his main event days in K-1 kickboxing he would rarely fight after 9 or 10pm.
"It doesn't matter whether it's going to be tough or not, it's too late to worry," Hunt told the Herald.
The Super Samoan has been on a tear to cut weight and acclimatise to Mexico City's altitude of 2250m above sea level since he took the fight to meet Werdum after UFC heavyweight champion Cain Velasquez suffered a knee injury.
