Singler Elbow to Hansbrough's Jaw

[dahoopref]

I'm just wondering why the officials didn't go to the monitor to confirm the elbow (which I'm sure the C saw). It was my understanding that any punch/elbow needed to be review with a monitor to make sure it wasn't thrown intentionally.

I remember a case where an official ejected a player where he thought the player threw a punch. He did not review the play on the monitor. The replay showed that the player did not throw a punch and was unjustly ejected. A memo from that conference came down that all possible punches/elbows were to be reviewed. Unfortunately the official who ejected the player was suspended for one game.
