The 38-year-old Broomfield, Colo., native is 11-4 as a pro and owns notable wins over the likes of Amanda Nunes, Miesha Tate, Marion Reneau and Raquel Pennington.
Parker, meanwhile, earned finishes in her first four professional outings under the Valor Fighting Championship banner. The 39-year-old Knoxville Martial Arts Academy representative came up short in her most recent bout at Invicta FC 40, where she was submitted by Chelsea Chandler in 65 seconds.
