Episode 7 of “The Ultimate Fighter 28: Heavy Hitters” opens with the fighters welcoming a battered Leah Letson back to The Ultimate Fighter house after her victory over Bea Malecki in the previous episode. Letson took a lot of damage in the fight with Malecki. Her eyes are swollen, and she has a bad cut on the forehead. She’s not discouraged, though, because after expressing some concern about the Team Whittaker coaches in the past, Letson says she’s happy with her situation. Team Whittaker’s Jan Francisco Espino Diepa , who was the third overall pick for his team, is preparing for his heavyweight quarterfinal bout against Team Gastelum’s top overall pick, Ben Sosoli . At 38, Espino Diepa is among the oldest athletes in the competition.
