Transgender mixed martial arts fighter Alana McLaughlin, a biological male, defeated her opponent via rear-naked choke in a Friday debut fight.

McLaughlin, 38, began transitioning in 2010 after leaving the U.S. Army Special Forces, Outsports.com reported. The transgender fighter beat Celine Provost, a biological female, 3 minutes and 32 seconds into the second round. McLaughlin began training in the sport a year ago and was cleared to compete against women by the Florida State Boxing Commission after a hormone level test.
