The strawweight bout between Mackenzie Dern and Amanda Ribas will now headline UFC Fight Night on Jan. 11, sources told MMA Mania's Alexander Behunin.
Dern-Ribas was originally scheduled to serve as the UFC Tampa co-main event Dec. 14.
Dern is looking to make it two consecutive wins after beating Loopy Godinez in August. The No. 6-ranked contender is 2-2 in her last four Octagon appearances dating back to last year.
Ribas is coming off a unanimous decision loss to former champion Rose Namajunas in a UFC main event in March. Ribas, ranked No. 8 in the division, is 1-2 in her last three outings.
