McGregor, 37, carries a 22-6-0 record and competes out of SBG Ireland. The southpaw stands five-foot-nine with a notably long 74-inch reach and lands 5.32 significant strikes per minute at a 49 percent accuracy rate. The Notorious has been away from competition, and the volume of testing he has completed this year signals a serious commitment to satisfying anti-doping requirements before his comeback.

Holloway enters the bout ranked fourth in the lightweight division and ninth in the pound-for-pound rankings with a 27-9-0 record. The 34-year-old from the United States trains out of Gracie Technics and is one of the most prolific strikers in the sport, posting 7.2 significant strikes per minute at 48 percent accuracy. Standing five-foot-eleven with a 69-inch reach, Blessed operates from an orthodox stance and has built his reputation on relentless output and durability.
