This Saturday, at UFC 146, the main card will feature strictly heavyweights.
From Junior dos Santos vs. Frank Mir to Roy Nelson vs. Dave Herman, Lavar Johnson vs. Stefan Struve to Stipe Miocic vs. Shane Del Rosario, the UFC's most evolved division will once again undergo changes.
However, through all those fights, including the championship bout, Cain Velasquez vs. Antonio "Big Foot" Silva could steal the show.
Not only does it mark the arrival of Silva to the UFC, but it serves as the return of Velasquez since losing his title to dos Santos at UFC on FOX 1.
Here's how they stake up in this UFC 146 head-to-toe breakdown.
