Round 1: Both fighters open orthodox. They both open with punches. Rousey eats a jab, but lands one of her own, plus a knee. Davis is hurt and before she can react, is snatched up with a harai goshi. From scarf hold, Davis takes almost a dozen unanswered punches, which puts the lights out. The referee has to save her.
