The Ultimate Fighting Championship announced Saturday night that McGregor (21-3), who won the featherweight title in December with a 13-second knockout of Jose Aldo, has relinquished the belt back to Aldo, who was declared the undisputed champion.
The Brazilian, who hadn't lost in 10 years before being dropped by a McGregor punch, rebounded to defeat former lightweight champion Frankie Edgar in convincing fashion at UFC 200 in July.

The UFC announced the Holloway-Pettis winner "will face Aldo in 2017 for the unified belt."
