Melquizael Costa will look to extend his win streak when he faces off against Arnold Allen in the main event of UFC Vegas 117 on Saturday. Since his second-round knockout loss to Steve Garcia back in December 2023, Costa has been on a tear, winning six consecutive fights. He was last seen in the Octagon in February at UFC Houston, where he became the first fighter to finish Dan Ige, landing a highlight-reel spinning back kick. DraftKings sees Costa as the underdog with a salary of $7,600.

Arnold Allen will look to get back in the win column when he takes on Melquizael Costa in the main event of UFC Vegas 117 on Saturday. Allen was last seen in action in January at UFC 324, where he suffered a unanimous decision loss to Jean Silva. Allen is actually 1-3 in his last four fights; however, he fought the best featherweight division has to offer, like former featherweight and BMF champion Max Holloway, Movsar Evloev, and already mentioned Silva. DraftKings sees Allen as the favorite with a salary of $8,600.

Daniel Santos will look to extend his win streak when he faces off against fan-favorite Dooho Choi in the co-main event of UFC Vegas 117 on Saturday. He earned his spot on the UFC roster in 2022, but he suffered a unanimous decision loss to Julio Arce in his UFC debut. Since then, Santos has won four fights, two fights by decision and two fights by knockout/TKO. He was last seen in the Octagon in October at UFC 320, where he defeated JooSang Yoo via second-round TKO. DraftKings sees Santos as the favorite with a salary of $8,400.

Juan Diaz is scheduled to make his UFC debut against Malcolm Wellmaker on the main card of UFC Vegas 117 on Saturday. Diaz earned his UFC contract in his last fight at Dana White's Contender Series, where he finished Won Il Kwon via second-round knockout by landing a spinning back elbow. He is currently on an eight-fight winning streak. DraftKings sees Diaz as a huge underdog with a salary of $7,000.
