I didn't see it. Too quick.
If you google "Ravens Chris Johnson" though, the first two links that come up...
Did the Ravens’ Defense ‘Take Out’ Tennessee’s Chris Johnson?
Did Ravens Intentionally Try to Take Out Titans' Chris Johnson?
I personally thought they tried to injure him. CJ was tearing through them with 100 yards in the first half. Titans did nothing in the second half without him.
....maybe a bit poor taste there
