Should Eagles Have Been Penalized

No one will for get the Philly Special call that resulted in a touchdown on fourth and goal for the Eagles in their Super Bowl win over the Patriots. Nick Foles fooled the Pats D when he lined up at H back and went out for a TD reception. Was it legal though? It certainly doesn't look legal as there only appears to be six players on the line of scrimmage which is not enough; there needs to be seven.
