Demian Maia has agreed to step in as a replacement for Santiago Ponzinibbio, facing Kamaru Usman in the main event of UFC Fight Night 129.
The card takes place from the Movistar Arena in Santiago, Chile and airs live on FOX Sports 1.
An injury to Ponzinibbio forced him out of the bout and opened the door for Maia to return to action. The former title challenger is coming off back-to-back losses to Colby Covington and current UFC champion Tyron Woodley.
Also, Ray Borg has pulled out of a fight with Brandon Moreno after his newborn son was forced to undergo brain surgery. Stepping in as a replacement to face Moreno is Alexandre Pantoja.
