N.C. State/Purdue (Video)

[refinks]

I'm hoping someone can upload the video once the game is over, but at about the 14:30 mark (give or take) of the second half, N.C. State player beaten badly down low. Purdue players goes for lay-up, N.C. state player gives what looked to be a clear 2 hand shove in the back. Officials called the foul, then went to monitor to review it, but stayed with a common foul.

To me, this is about as clear of a flagrant 1 as you can get. Anybody see anything that might have caused the crew to stick with a common foul?
