Gabs das hier schon, habe es auf die Schnelle nicht gefunden? Die organisieren Bareknuckle Kämpfe, hab mir 2-3 angeschaut, meist sehr schnell vorbei:

KING OF THE STREETS IS A REAL UNDERGROUND FIGHT CLUB WHERE YOU CAN FIGHT FOR PRIZE MONEY.

- 5 kg difference is allowed in the fight club.
- No rounds and No rules.
- Submissions is only allowed if both parts accept it.
- Only way to win is by KO or referee stoppage. Only winner gets the prize money.
(Achtung, nix für zartbesaitete Gemüter):
