What does that punch at the end of the game mean?

Anyone have and idea what the typical punishment for throwing a punch Trent Cole did is? Will he miss next week too? It didn't look like the worst thing in the world to me, I mean Ohara definitely hit him in the face first.

It would suck to see a suspension of Cole for more than the 8 last seconds of this game. Our defense is scaring me because it seems a little porous as it is.
