Ultimate Fighting Championship (UFC) is just over 24 hours away from its upcoming UFC Vegas 101 mixed martial arts (MMA) event, headlined by a 115-pound showdown between strawweight rivals Mackenzie Dern and Amanda Ribas. The action gets underway this Sat. night (Jan. 11, 2025) on ESPN+ from inside the promotion’s APEX facility in Las Vegas, Nevada, and also features a welterweight co-headliner between 170-pound stalwarts Santiago Ponzinibbio and Carlston Harris.
Before the ESPN+ live stream gets underway this weekend in “Sin City,” which includes the all-action middleweight contest pitting Chris Curtis against Roman Kopylov, all 28 fighters must hit the scale to prove themselves worthy. Note: Nevada State Athletic Commission (NSAC) affords a one-pound allowance in non-title fights.
