LAS VEGAS – “The Ultimate Fighter” returned this week for its 27th season, and for the first time all the cast members are unbeaten heading into the show.

MMAjunkie recently sat down with all 16 cast members. Watch the video above to get to know featherweight Tyler Diamond (9-0), who took his first fight on an hour’s notice not long after graduating high school. He beat up a 37-year-old opponent and thought, “I might be pretty good at this.”

“The Ultimate Fighter 27,” featuring UFC heavyweight champion Stipe Miocic and light heavyweight champ Daniel Cormier as coaches, airs Wednesdays at 10 p.m. ET on FS1.
