With its doubleheader on Saturday in Belfast, Northern Ireland, and Sao Paulo, Brazil, the Ultimate Fighting Championship will cross the 100-event threshold in its UFC Fight Night series. It debuted on Aug. 6, 2005 on Spike TV as a supplement to the UFC’s pay-per-view schedule and in the 11-plus years since has provided MMA audiences with countless unforgettable memories: Rashad Evans’ head kick knockout on Sean Salmon, Josh Neer’s bloody triangle choke on Melvin Guillard and Chan Sung Jung’s twister on Leonard Garcia, to name but a few.
