UFC 308, Sat at 8am (main card), featuring Max Holloway from Waianae and Dan Ige from Kahuku; locations showing the fight
4am prelims, 8am main card, in Abu Dhabi.
Dan is the second fight on the main card, so a bit after 8am.
Max is fifth and last, so probably around 10am.
Not much is open for the 4am prelims, but there are plenty of locations showing the main card.
