Raul Rosas Jr. will be heading to the Octagon next month.

The 18-year-old Mexican American mixed martial artist, who was the youngest fighter signed to the UFC last year at 17 years old, will attempt to get back on track at the UFC‘s Mexican Independence Day show.

Rosas Jr., a bantamweight, will face Terrence Mitchell at Noche UFC on September 16 in Las Vegas, according to ESPN.

ESPN Deportes‘ Carlos Contreras Legaspi first reported the bout set for Noche UFC, which is a larger-sized UFC Fight Night card in celebration of the Mexican holiday at T-Mobile Arena.

Rosas Jr. (7-1) earned his way into the promotion from Dana White‘s Contender Series. Rosas Jr. won his UFC debut at UFC 282 in December but then fell to Christian Rodriguez via unanimous decision at UFC 287 in April.

Mitchell (14-3), a 33-year-old from Alaska who competed on “The Ultimate Fighter” in 2016, lost in his UFC debut to Cameron Saaiman by first-round TKO at UFC 290 last month.
