UFC 216 is headlined by an interim lightweight championship bout between Tony Ferguson and Kevin Lee, while flyweight title holder Demetrious Johnson defends his belt against Ray Borg in the night's co-main event.
"Where you at McNuggets?" he yelled into the mic.
Ferguson, a former Ultimate Fighter victor, became the interim champion when he submitted Lee in the third round. After almost submitting a fading Lee (16-3) in Round 3 with an armbar, Ferguson locked in a triangle choke to force the tap at 4:02.
Winning streak: Demetrious Johnson.
Lee (16-3) said dropping 19 pounds less than 24 hours before Friday's weigh-in and battling through a staph infection he said he kept secret was "too much to handle ... but Tony Ferguson was the better fighter tonight".
However, as Nate Diaz is the only fighter to carry a win over McGregor, some fans feel this entitles him to a shot at the title as the No.1 contender Khabib Nurmagomedov has not been active.
Then, Ferguson wrapped his legs around Lee's head and neck and squeezed, forcing Lee to tap out 4 minutes, 2 seconds into the round.
"This fight went exactly the way I wanted it to be", Ferguson declared at the match's end.
"I was saving my good material for him [McGregor]. He was slippery (when applying the finishing squeeze) but I just used textbook (skill)".
"Tony's the toughest fight in this division", Lee said. Plus, it doesn't sound like McGregor is in any kind of hurry to fight again.
What's a UFC event without a little pre-fight weigh-in chaos and uncertainty?
The delay certainly worked in Mighty Mouse's favour, as he broke Anderson Silva's record for the most consecutive title defences in UFC history, stretching that number to 11 and if you know Johnson, you know he doesn't do things by halves.
Johnson's historic victory came by a stunning armbar submission of No.3-rated flyweight Ray Borg.
