Jason Spezza might have eyes in the back of his head

Though the halcyon days of Ottawa Senators forward Jason Spezza racking up 50 assists per season (or more) are all but over, the Senators captain proved on Tuesday that he still has a trick or two up his sleeve.

Has it ever been proven definitively that Spezza doesn't have eyes in the back of his head? Or on the back of his neck, maybe, since his helmet would theoretically cover the eyes on the back of his head (presuming they exist, which they totally might).
