According to MMAWeekly.com:
In a battle of lightweight champions, Dream’s Shinya Aoki immediately put Sengoku’s Mizuto Hirota on the mat and took mount with Hirota’s arm wrapped up and behind his own back. Aoki then proceeded to, quite literally, break Hirota’s arm in an odd sort of twisting armbar. The maneuver popped Hirota’s elbow out of place, leaving his forearm flaccid.
