All hearsay/rumors from people at the event.
One rumor I heard was whatever the medical issue was that stopped Nate from being medically cleared cause him to lash out at somebody..... who..... dont know. But I guess Marquardt was clearly the aggressor and started a scuffle with someone. Dana? Athletic Commission member? Ref?..... Im sure we will find out tomorrow. This is all rumor mill though.... but it goes along with medically not being cleared.... and then Dana being PISSED afterwards and banning Nate from the UFC.... similar to Paul Daley. Punches thrown = getting tossed.
