The UFC's plans for UFC 272 lasted about two days.
Former featherweight champion Max Holloway pulled out of his title rematch against current champ Alexander Volkanovski after aggravating an injury Thursday, according to ESPN's Brett Okamoto.
Dana White announced the Volkanovski-Holloway fight on Tuesday, setting up a trilogy. In the two previous bouts, Volkanovski won a unanimous decision and split decision.
Volkanovski is currently the promotion's No. 2 pound-for-pound fighter.
Since his second loss, Holloway has defeated Calvin Kattar and Yair Rodriguez to stay on top of the contenders.
