The UFC rolls into its second single-day doubleheader in the past month on Saturday as UFC Fight Night 43 marks the organization’s debut fight card in New Zealand.

Auckland’s Vector Arena will play host to the first of two UFC events in a 24-hour stretch as UFC Fight Night 43 goes down in the wee hours of the morning for Stateside fans before the latter offering, UFC Fight Night 44, happens in Texas during the evening.

Headlining the event will be two athletes in desperate need of a victory as Kiwi fighter James Te Huna (16-7 MMA, 5-3 UFC) looks to snap a two-fight skid with a drop to the middleweight division against former Strikeforce champion Nate Marquardt (32-13-2 MMA, 10-6 UFC), who is moving up to 185 pounds after a four-fight stint at welterweight.

Marquardt has proven to be a far more successful fighter at middleweight through his career, and his statistics reflect that point. For more on what kind of numbers “The Great” and the 19 other participants on the card will bring into the event, check out 50 pre-fight facts for UFC Fight Night 43.

Te Huna vs. Marquardt is the first main event in UFC history where both fighters enter the contest with back-to-back losses inside the octagon.
