Thursday's news conference marks the first time these two will meet face to face since that fateful moment when an out-of-his-mind McGregor threw a hand truck at a bus containing Nurmagomedov.
Regardless, McGregor has finally met his trash talking match in Nurmagomedov.
It might be easy for the uninitiated to read Nurmagomedov's last name, take in his thick Russian accent and assume he's a trash talk nonstarter, someone who would take the box turtle approach and fend off McGregor with pure opacity.
With Hand Truck Gate still fresh in everyone's minds, and with these egos involved, Thursday is about as can't-miss as can't-miss television can be.
For all his faults, McGregor is a great fighter and a smart guy.
