Why wasn't Shuster ejected for the killdrop hit on Burfict and immediate taunt?

I feel like Vontaze Burfict is our Batman. The only player who can scare the Steelers.

Except now, the Steelers own us SO much, they got their Bane in the form of JuJu. Now we have no hope anymore.

It sucks even more that it was the rookie who did it to him.
