We've seen plenty of freaky sports injuries in the past. But, we've never seen one quite like this.

Last night, Spurs guard Stephen Jackson fired up a three-pointer during the first quarter of the Spurs/Knicks game at Madison Square Garden. Then, he took a few steps backwards as he watched his shot arc towards the basket. And, as he did, he accidentally fell over a waitress who was serving something to New York City Mayor Michael Bloomberg. Bloomberg was sitting courtside to watch the game.

Jackson had to leave the game with a sprained ankle. What a crazy injury.
