That nikka collapsed onto his back, he wasn‘t moving, he was falling
once he stopped intelligently defending himself and his legs gave out, he gave the referee opportunity to stop the fight so it’s his fault and no one else.
you think falling is failing to defend oneself/grounds for stoppage? that shouldn't even happen in a regular fight, unless it's a head bouncing walk off KO.
dern could have got stopped like that tonight the first or second time she fell, but the ref wanted clarity. title fights need more clarity.
