Flex Fight Series has spent sixty-one cards building a regional circuit, and this is the night it moves inside Madison Square Garden. The Infosys Theater is a real step up from the promotion's usual rooms, and it is billing the card as the biggest in its history. Twenty-two bouts of MMA and kickboxing puts prospects, veterans and amateurs on one bill, which is how you end up watching somebody's first professional win.
What to expect
A long card of twenty-two professional and amateur bouts across mixed martial arts and kickboxing, working up from the amateur preliminaries to the headline fights. Seating is theater style around the cage rather than arena bowl seating, which puts you closer than a Garden ticket normally would. Doors open an hour before the first bell.
Good to know
- This is a combat sports card of mixed martial arts and kickboxing, not a bodybuilding or physique competition.
- The Infosys Theater is a separate room inside the Madison Square Garden complex, not the main arena bowl.
- Entry is off Seventh Avenue, between West Thirty-First and West Thirty-Third Streets.
- A card of this length runs well past its scheduled start, so the headline bouts land late.
- The promotion's cards are typically carried on Fubo Sports for anyone who cannot make it in person.
