New "Iron Chef" growing rusty?

I may have missed an episode of Iron Chef (Food Network), but has Michael Symon been on yet as a competitor? The only time I remember seeing him on was when he and John Besh were battling it out for the title of "The Next Iron Chef." I loved Symon during the series that led to his selection, and I was hoping he'd be picked more. For some reason, Bobby Flay and Mario Batali are almost always chosen. Rarely do you see Cat Cora or Morimoto.

Iron Chef is a regular viewing option in our house. My boy loves Bobby Flay, and I think Mario Batali is too cool. The show is a great way to see intense kitchen skills, and, believe it or not, you can actually get some interesting ideas from it.
