“Put me in,” Diaz, who remains one of the most enigmatic figures in the sport, posted on Thursday.
Diaz was thought to take another extended hiatus from MMA following his Sept. 25 defeat to Lawler but the loss appears to have reignited his desire to compete again.
The 38-year-old hasn’t won a fight in over a decade but remains one of the most popular fighters in the sport. Diaz’ last win came in 2011 when he beat UFC Hall of Famer B.J. Penn from pillar-to-post in a three-round slugfest at UFC 137.
