It's time for the Ultimate Fighting Championship's second card on ABC, and the promotion's put together a solid five-fight slate for an appropriately titled UFC on ABC 2 event. What initially could've served as a title eliminator in the main event is now an opportunity for Marvin Vettori to stake his claim as a contender, as he faces late replacement Kevin Holland. Past that, two fights in particular stand out: top featherweight prospects Sodiq Yusuff and Arnold Allen clash in a co-main event that serves as the best fight on the card, and Mackenzie Dern attempts to break through to true contender status against the returning Nina Nunes (formerly known as Nina Ansaroff).
