I wasn't quite sure if it was that initial hit that rattled him or that sleeper hold that Chase Young tried to put him in on the way down. I actually thought forearm to the neck was a more dangerous hit than the initial hit was. They could've called targeting on both if they wanted to enforce the rule to the letter since Young's hit was "forcible contact above the shoulders on a defenseless ball carrier" (since he was going to the ground in the arms of a teammate with his forward progress stopped). I'm glad they didn't though.
