Brian Melancon will end his MMA career after 10 fights, including two at the sport’s highest level. The 31-year-old Texan on Wednesday announced his retirement from the sport, citing ongoing kidney issues and a doctor’s recommendation. He was scheduled to meet Robert Whittaker next month at UFC Fight Night 33 in Australia, but earlier today that bout was scrapped and Melancon made his retirement official right afterward on his Facebook account.
