Conor McGregor returns to MMA for the first time in two years on Saturday when he takes on defending lightweight champion Khabib Nurmagomedov at UFC 229 in Las Vegas.
McGregor's (21-3) last bout was a 10th-round defeat to Floyd Mayweather during his pro boxing debut a year ago.
The former two-division champion has fierce competition, however, as Nurmagomedov (26-0) has rarely been challenged in a fight. Nurmagomedov's last UFC bout was his title-winning match against Al Iaquinta at UFC 223, an effort he controlled from start to finish.
The fight will be the first for the duo since the infamous bus incident in Brooklyn in which McGregor was arrested for misorderly conduct after throwing several objects at Nurmagomedov's bus.
