This page reproduces publicly reported regulatory and medical-administrative records. Every entry names the body that issued it. Anti-doping testing entries are counts of publicly reported test sessions and are not pass/fail results — a test session is not a positive test. Records are reproduced as published and are not medical advice.

Bantamweight contender Aljamain Sterling and former TUF Latin America winner Alejandro Perez will have to wait a little longer for their return to the Octagon, as injuries have forced both to withdraw from events in Albany and Las Vegas, respectively. New York's Sterling was scheduled to face Raphael Assuncao on the December 9 UFC Fight Night card in Albany. Perez's opponent for the TUF 24 Finale event in Las Vegas on December 3 was Rob Font. UFC officials are currently seeking replacement opponents for Assuncao and Font. Stay tuned to UFC.com for updates on both events.
