Volkanovski's post caught the attention of McGregor, who became the first person in UFC history to hold titles simultaneously in two weight classes when he won the lightweight championship in 2016 while also holding the featherweight belt.

Volkanovski refused to back down in his response:

Volkanovski is coming off a close unanimous-decision loss to current lightweight champion Islam Makhachev in February. Despite facing a significant size disadvantage, Volkanovski surprised many with how competitive the matchup turned out to be.

He's expected to make his long-awaited return to the Octagon later this year against Michael Chandler, who he coached against in the upcoming 31st season of The Ultimate Fighter reality competition series.
