It's only fitting Urijah Faber's career will end on a fight card sandwiched between super shows powered by lighter-weight stars. Faber, whose run as World Extreme Cagefighting featherweight champion back when that belt was the undisputed world title at 145 pounds paved the way for smaller fighters as headliners, announced on MMAFighting.com this week that his Dec. 17 fight in his hometown of Sacramento against Brad Pickett will be the final contest of his career. UFC on FOX 22 falls between events headlined by the two biggest drawing cards in mixed martial arts today — UFC featherweight champion Conor McGregor, who headlines UFC 205 in New York City on Nov. 12, and women's bantamweight superstar Ronda Rousey, who makes her return at UFC 207 against current 135-pound champion Amanda Nunes.
