'UFC 218 Countdown' full episode, with Holloway-Aldo 2, Ngannou-Overeem and Alvarez-Gaethje

The one-hour special previews the card’s featherweight title fight between champion Max Holloway (18-3 MMA, 14-3 UFC) and the man he took the belt from, now-former champ Jose Aldo (26-3 MMA, 8-2 UFC). Holloway was supposed to fight former lightweight champ Frankie Edgar in the headliner until Edgar pulled out with an injury, giving way to an immediate rematch for Aldo.

The show also dives into the co-main event heavyweight contenders showdown between Francis Ngannou (10-1 MMA, 5-0 UFC) and former Strikeforce champ Alistair Overeem (43-15 MMA, 8-4 UFC). The card also features a fight between “The Ultimate Fighter 26” coaches Eddie Alvarez (28-5 MMA, 3-2 UFC), a former UFC and Bellator champ, and Justin Gaethje (18-0 MMA, 1-0 UFC), a former WSOF champ.

“Countdown’ goes behind the scenes with all six fighters, and you can watch the full episode above.
