Below, via TMZ, is the punch that got Ravens running back Ray Rice a two-game suspension from the NFL. The woman on the other end of that left hook is Janay Palmer, who is now Rice's wife.
Here's just the punch:
Until now, the public had seen only the aftermath of the video—Rice dragging an unconscious Palmer out of the elevator and into the lobby of an Atlantic City casino. According to Peter King, among others, NFL commissioner Roger Goodell had access to the full video, including the clip you see above, as he weighed punishment for Rice. [Update: Peter King, among others, is now quietly walking back his own reporting on this.]
Both Rice and Palmer were charged with simple assault in the Feb. 15 incident. In March, a grand jury cranked up the charge against Rice to third-degree aggravated assault, a felony; the charge against Palmer was dropped altogether. In May, Rice entered a diversionary program that would allow him to avoid trial. Upon completion of the one-year program, his assault charge will be dismissed.
