A welterweight title match between Tyron Woodley and Nate Diaz has been widely rumored to headline UFC 219, although neither the Diaz camp nor the Woodley camp has confirmed this to be true as of now.
Woodley (18-3-1) most recently successfully defended his UFC Welterweight title against welterweight contender Demian Maia at UFC 214 in July, a fight that ended in Woodley’s favor via Unanimous decision after five rounds.
Nate Diaz (19-11) last appeared in the octagon August 20, 2016 in a fight that ultimately ended in a loss via majority decision in favor of Conor McGregor.
