Underground is not standard MMA
OKTAGON Underground combines stand-up fighting with small MMA gloves. Unlike standard MMA, it does not feature sustained ground fighting with ground-and-pound or submissions. A takedown can still matter: control the position for at least three seconds and it counts, then the referee restarts the action standing. The rules announced for the individual bout remain decisive.
Rounds and permitted techniques
A bout has three three-minute rounds. If it ends in a draw, an additional three-minute round is provided for. Punches, kicks, elbows and active clinch work are allowed. Trips and throws can also be used. A grounded or kneeling opponent must not be attacked.
Scoring and stoppages
Three judges score the rounds. OKTAGON lists near-knockouts, damage, striking combinations and earned takedowns or takedown defense among its criteria. A winning round is normally scored 10–9, a dominant one 10–8; 10–10 is also possible. The referee may stop a bout by TKO when one fighter is overwhelmingly outmatched.
Do not confuse it with Stand & Bang
OKTAGON also stages the separate Stand & Bang format. Its rules do not automatically apply to an Underground bout. Always check the special rules named for the particular fight. For the regular sport, see MMA rules explained.
