The fight between the former UFC 145-pound champion Holloway (22-6) and Rodríguez (13-2) was likely to determine the next challenger for the featherweight title after champion Alexander Volkanovski defends his belt against Brian Ortega later this year.
Volkanovski and Ortega are currently the coaches for this season of “The Ultimate Fighter.”
Rodríguez hasn’t fought in nearly two years, with his last bout coming in October 2019 against Jeremy Stephens.
Holloway opened his 2021 UFC schedule with a stellar performance against Calvin Kattar. UFC is expected to determine a new main event for that date in the upcoming days.
