House M.D....

I think I saw him at the beginning of an episode of House called Mirror Mirror, but the character I think he played isn't listed in the cast for that episode. Here's a link to that episode-> http://www.youtube.com/watch?v=GcaxKY2AAu4
Without having to pay it just shows a "preview" (which is just the first two minutes) of the episode. I think he is the thug wearing the wool hat. Can anyone confirm or disprove this?
