The phrase “biggest card to date” has been tossed around when describing a night of mixed martial arts action but for once, the meaning is literal as the UFC presents its first heavyweights-only main card this Saturday with UFC 146. Newly-crowned champ “Cigano” Junior Dos Santos (14-1) takes on former champion and lethal submission artist Frank Mir (16-5) in the night’s main event. Cain Velasquez (9-1) begins his quest back to the title when he welcomes “Bigfoot” Antonio Silva (16-3) from the Strikeforce ranks. ”Pee Wee” Dave Herman (21-3) battles “Big Country” Roy Nelson (16-7) in the card’s anchor. Undefeated streaks are on the line when UFC prospect Stipe Miocic (8-0) plays host to Shane Del Rosario (11-0) in his promotional debut from Strikeforce. The card’s opener is sure to draw heads as “Skyscraper” Stefan Struve (23-5) and “Big” Lavar Johnson (17-5) are tied to do battle. Both Struve and Johnson have shown the best way to get the job done is to leave out of the judges’ hands. Come Saturday night, they will look to do just that.
