Fabricio Werdum started the week as a big underdog and will end it as a big favorite on the UFC 180 betting odds menu.
The challenger for the heavyweight title was a big underdog to Cain Velasquez for the UFC belt on November 15 in Mexico City, but the champ hurt his knee.
The UFC asked Mark Hunt to step in and the 40-year-old Samoan agreed to fight, just months after defeating Roy Nelson.
Werdum, a Brazilian jiu-jitsu world champion, opened as a -260 favorite while Hunt, a former kickboxing world champion, was a +200 underdog at Bodog which was the first online sportsbook to post odds on the fight.
The fight card also includes Jake Ellenberger vs unbeaten Kelvin Gastelum and Diego Sanchez vs Joe Lauzon on the main card.
Ricardo Lamas vs Dennis Bermudez is another top fight on the UFC 180 betting menu.
