Jeremy Botter@jeremybotterMMA Senior WriterMarch 15, 2013

MONTREAL—We're just over 24 hours away from a fight that will (hopefully) warm up the frigid weather here in beautiful Quebec. On Saturday night, Georges St-Pierre and Nick Diaz will finally settle their long-standing differences at the Bell Centre.

But before that happens, I decided to bring in pre-eminent Canadian journalist "Showdown" Joe Ferraro for another look at the UFC 158 fight card. This time around, we're giving you our pick for the biggest potential upset on the entire card, and we'll tell you why each of us picked who we did.

Now, it's your turn. Who is your pick for the biggest upset of UFC 158 and why? Tell me in the comments below, and tell me why.
