Instead of a rerun of High Potential, viewers of ABC will see a 60 minute instant special on the U.S.-Iran conflict, a last minute scheduling change that's probably not even in your DVR guide yet. 

"Shockwaves: The Attack on Iran" will look at what's happened this weekend, what might be next and how long this could go on. It begins at 9:01 PM. 

So far, no word if any of the other major over-the-air networks have their own plans for a special but CBS - the top rated broadcast network on Sunday nights - has not aired new episodes of their series in months. They might be reluctant to interrupt their return.
