Shannon Knapp promotes the best MMA fights in Kansas City. In April, Knapp's women-only MMA fight group, Invicta Fighting Championships, hosted the return to the cage of Cristiane "Cyborg" Justino, who had served a yearlong steroid-related suspension. Cyborg mauled opponent Fiona Muxlow on the way to a first-round TKO. The brutal fight wasn't even the best of the night. Invicta FC 5 was filled with GIF-worthy highlights: Rose Namajunas submitted Kathina Catron in 12 seconds with a flying armbar (submission of the night); Miriam Nakamoto knocked out Jessamyn Duke with a pair of knee strikes (KO of the night); and Leslie Smith and the UFC's Sarah Kaufman slugged it out (fight of the night). Knapp's cards give new meaning to fighting like a girl.
