Green was the last fighter to weigh in Friday morning at the UFC Apex in Las Vegas and hit the lightweight limit at 156 pounds. He walked to the scale and stepped on without assistance.
When it came time for the pre-fight faceoffs about 25 minutes later, Green and Miller did not participate. UFC president Dana White explained why during his scrum with reporters.
“Bobby Green just collapsed back there,” White said. “Doctors are looking at him. They’re trying to rehydrate him right now.”
Later Friday, the UFC announced that Green vs. Miller was pulled from UFC 258. Stepping into its main-card spot will be a featherweight bout between Brian Kelleher and Ricky Simon.
There is no word on Green’s condition at this time.
Green (27-11-1 MMA, 8-6-1 UFC) was looking to rebound from a unanimous decision loss to Thiago Moises last October, which snapped a three-fight winning streak. Miller (32-15 MMA, 21-14 UFC) also aimed to get back in the win column after dropping a decision to Vinc Pichel last August.
With the change, the finalized UFC 258 lineup includes:
MAIN CARD (Pay-per-view, 10 p.m. ET)Champ Kamaru Usman (170) vs. Gilbert Burns (170) – for welterweight title Maycee Barber vs. Alexa Grasso Kelvin Gastelum vs. Ian Heinisch Brian Kelleher vs. Ricky Simon Julian Marquez vs. Maki Pitolo
