While boxing can be appreciated for the technical maneuvers that occur during a three-minute round, and MMA has fans cheering for its almost-anything-goes modus operandi, there’s one thing fans of hand-to-hand and toe-to-toe combat might certainly miss: the knockout.

Big Knockout Boxing helps marry those two fighting worlds, facilitating an environment that gives the boxers maximum opportunity to take down their opponents. Big Knockout Boxing was created by a team of industry veterans and is licensed by the Nevada State Athletic Commission, with the premiere event taking place Saturday, Aug. 16, at Mandalay Bay Events Center.

Rounds last only two minutes, with five rounds for nonchampionship bouts and seven rounds for championship bouts. The fighting space (“The Pit”) has no ropes or corners and is significantly smaller—just 17 feet in diameter—than traditional boxing rings. The smaller space forces fighters into confrontation. A padded “safety zone” lines the outer portion of The Pit, so fighters may retreat as a measure of safety but only for a standing count of eight by the referee.

Saturday’s main Big Knockout Boxing event in Las Vegas pits Cedar Park, Texas, native Bryan Vera against Philly’s Gabriel Rosado as they battle for the middleweight world championship.
