A key welterweight contest has been booked to headline the UFC’s first visit to Chile.

UFC officials today announced that a previously reported matchup of Kamaru Usman (12-1 MMA, 7-0 UFC) vs. Santiago Ponzinbbio (26-3 MMA, 8-2 UFC) will, indeed, headline UFC Fight Night 129.

The card takes place May 19 at Movistar Arena in Santiago, Chile. While the bout order has yet to be finalized, the night’s main card airs on FS1.

Usman is currently ranked No. 8 in the latest USA TODAY Sports/MMAjunkie MMA welterweight rankings, while Ponzinibbio is an honorable mention.

Ponzinibbio is riding a six-fight winning streak. He’s beaten notables such as Mike Perry, Gunnar Nelson and Zak Cummings during a run dating back to his June 2015 loss to Lorenz Larkin.

With the main event spot in Chile, Ponzinibbio, from nearby Argentina, will hope to elevate the sport in the UFC’s first non-Brazil event in South America.

Attempting to play spoiler for Ponzinibbio will be Usman, the only member of the 170-pound division who has a longer active winning streak in the division. Usman is riding seven consecutive wins and has been begging for a breakthrough opportunity against a relevant opponent. He will get that at UFC Fight Night 129.

The UFC Fight Night 129 lineup currently includes:

• Kamaru Usman vs. Santiago Ponzinibbio
• Volkan Oezdemir vs. Mauricio Rua
• Chad Laprise vs. Vicente Luque
