VIDEO: Is that Bears legend Mike Ditka wearing a Packers jersey?

It seems as though Mike Ditka has a doppelganger out there causing trouble.

Pro Football Hall of Famer Jerry Rice caused a ruckus among Chicago Bears fans when he tweeted a video of a man - who bears an uncanny resemblance to the Bears icon - sporting a Green Bay Packers jersey.

Did Ditka lose a bet or something? Did the videographers catch him filming a commercial? And why No. 45 and not his usual No. 89?

And if this is actually not him, does he know that he has a long-lost twin?

We need answers.
