Ultimate Fighting Championship (UFC) photographer extraordinaire, Josh Hedges, was on the scene at the MGM Grand Garden Arena earlier today (May 23, 2012) to shoot several of the notable fighters who will compete on the UFC 146: "Dos Santos vs. Mir" main card for the event's open media workouts.

Naturally, the two men who will collide in the main event of the evening, Junior dos Santos vs. Frank Mir, were on the scene to promote their Heavyweight clash, which is for "Cigano's" division title.

The other main card fighters who will be featured on the pay-per-view (PPV) broadcast -- Cain Velasquez, Antonio Silva, Roy Nelson, Dave Herman, Shane del Rosario, Stipe Miocic, Lavar Johnson and Stefan Struve -- were also on the scene to work up one of the last few real sweats prior to fight night (May 26, 2012) at the MGM Grand Garden Arena in "Sin City."
