Should Kasey Kahne be penalized?

I want positive answers,I have been watching Nascar for 12 years so I've seen my share of dirty driving but I have to say what Kasey Kahne did today has to be the dirtiest driving I have ever seen.Glad to see Jeff and Sam walk away but Jeff's back is injured again because of dirty driving.This could end one of the greatest careers the sport has ever seen sooner than it should. Jeff can only take so much pain,and the worst thing is Jeff was in the wrong place at the wrong time.
