Here is an article that includes the new targeting rule for 2019: The new rule no longer allows referees to “stand” with the play as called, meaning targeting penalties will be imposed only when they clearly withstand more scrutiny.

Here is what was said in another article:
Targeting: This is a good news, bad news scenario for the call that causes more confusion than any other in the game. First, the bad news. The standard half-game suspensions for targeting -- forcible contact to the head, neck or shoulders of a defenseless player -- will remain intact, but a player who is ejected for the third time in a season will be forced to miss the entire next game no matter when that third (or subsequent) foul takes place.
Now the good news. You'll likely see targeting calls decrease because calls that would merely "stand" based on the ruling on the field will no longer exist. All targeting calls will still be referred to the replay booth, but the booth will now have to "confirm" the call on the field in order for a targeting foul to stand. If it can't be confirmed, it will be overturned.
I like the if it can't be confirmed, the call is overturned. This should cut down on the questionable targeting penalties and gives the best opportunity for the refs in the booth to get it right.
