SDSU v. New Mexico, Shot Clock Violation?

Anyone watching the SDSU v. New Mexico game? With 2:22 left in second half New Mexico drives for a layup and hit no rim. Offensive rebound by New Mexico, but shot clock expires before the ball is out of shooters hand. Officials either do not hear the buzzer, or just miss it. Steve Fisher requests a time out immediately after the play and (I think) asks the officials to review the shot on the monitor. Replays clearly show the shot clock expired before the ball was ever released, yet the officials do not overturn the basket. Is there a particular NCAA rule where they are not allowed to overturn this shot? Or did the officials just kick it?

Edit: They just missed a shot clock violation on SDSU as well with about 11.2 sec to go. Now they have to figure out where to put the game clock. Announcers say this is the second time SDSU has been burned, and I tend to agree :S

2nd Edit: This would be a good game to watch for newer officials so they can learn why game/situational awareness is so important.
