During the TV broadcast, I honestly thought it was a cheap shot choke hold.
Watching the replays (and I haven't noticed one in this thread that shows the sequence all the way up until Hurts begins to get off the ground), you can see that the hand that APPEARS to be grasping Hurts' neck is actually holding a wad of jersey about where his name is.
The "looking around" is the defensive player looking over at the ball, seeing a turnover, then holding Hurts down to keep him from pursuing.
I would be offended if this was a dangerous, cheap shot move. However, my impression is that it's really nothing (other than possibly a "holding" call that would never/should never be called at ANY level from peewee to NFL.)
I would bet my last dollar that if you could talk to Jalen, he was never in any pain and probably thought nothing of it.
