Watch The Ultimate Fighter Season 26 in Australia

Two top-seeded teammates discuss the possibility of having to face each other later in the tournament; a fighter shares the story of her lifelong battle with addiction; and a heavily-favored veteran takes on an underdog in the fourth preliminary fight.

After losing in the Octagon, one fighter skips training, causing a rift between her and her coach; two more flyweights face off in the fifth preliminary fight. Eddie Alvarez and Justin Gaethje serve as coaches.

Eddie Alvarez pulls out all the stops to give his team a competitive advantage; a fighter struggles with an old injury; and one of the most accomplished fighters in the tournament takes on a young rising star in the sixth preliminary fight.

Following a dominant win by No. 2 seed Barb Honchak to eliminate No. 15 seed Gillian Robertson, there are only two fights remaining in the opening round of the tournament to determine the first ever women’s flyweight champion in the UFC. This week, Team Alvarez sends Hungarian striker Melinda Fabian, the No. 7 overall seed, against Team Gaethje’s Rachael Ostovich-Berdon, who enters the tournament as the No. 10 seed. Fabian has been relatively quiet all season long, but she came under the spotlight for all the wrong reasons a week ago after suffering a hamstring injury that threatened to knock her out of the competition. Injuries on The Ultimate Fighter are commonplace, much like anywhere else in mixed martial arts, but Fabian joined Emily Whitmire as the fighters who have suffered through ailments with a shortened timeline until they must determine whether they can compete or drop out of the competition.

After a tough loss she can't forget, Lauren Murphy is unhappy on Team Alvarez and resents Eddie on how he handled training leading up to her fight. Eddie and Justin compete in the coaches challenge.
