TSN posted video from today's Los Angeles Kings practice that shows Jonathan Quick take a shot up high, skate around for a few minutes afterwards, and leave the ice. Although he did appear to be in a bit of pain, Dwight King also leaves practice the same time as Quick, so the paragraph about Quick being "forced" to leave practice after taking a shot to the collarbone area may not be 100% accurate. 

This is the shot he took that resulted in him skating around aimlessly until he hunched over the wall by the benches, and finally left after almost two minutes.

I don't know, he seems fine to me.
