It will be a matrimonial milestone for mixed martial arts.
This will mark the first time that a husband and wife compete in the same UFC event.
The De La Rosas were married in 2017, and they live in Fort Worth, Texas. Mark De La Rosa (11-3) is trying to bounce back from two straight losses. The 25-year-old returned to flyweight from bantamweight in his most recent bout, a defeat to Kai Kara-France at UFC Shezhen in August.
Montana De La Rosa (10-5) had a four-fight winning streak snapped by Andrea Lee at UFC Greenville in June. The 24-year-old Montana native has finished all three of her UFC wins by submission. Montana, like her husband, competes at flyweight (125 pounds).
UFC Rio Rancho will be headlined by a light heavyweight contender bout between Corey Anderson and Jan Blachowicz. The card will feature a welterweight bout between popular veteran Diego Sanchez and Brazilian up-and-comer Michel Pereira.
