Is this reviewable?

[Nevadaref]

Hightower, Burr, and Hillary went to the TV monitor with 2:52 remaining in the Georgetown @ Illinois game tonight for a shot clock violation.

Illinois attempted a try which fell just short of the ring and then the ball was batted by two players contesting for the ball. The ball appeared to just miss the ring again (not that it mattered here because this wasn't a try) and then was caught by an Illinois player who failed to release his try for goal prior to the shot clock horn sounding.

Burr waved off the basket. Hightower came over to him and after a short discussion the officials went and used the TV monitor. They ruled the ball did not hit the ring and the shot clock violation call stood.

I thought that this was not a reviewable play. It was my understanding that only near the end of the game (meaning with just a few seconds remaining) could the TV monitor be consulted for a shot clock violation. And then it would be to determine if the ball was released prior to the horn, not to judge whether or not the ball contacted the ring.

So NCAA folk here, what's the deal?
