Ultimate Fighting Championship (UFC) will once again go head-to-head with a major boxing match when it pits UFC on Fox 3: "Diaz vs. Miller" opposite the return of Floyd Mayweather, who will battle Miguel Cotto in a WBA light middleweight championship showdown.

Mayweather, of course, had his 90-day jail sentence pushed back just so he could compete one last time before getting sent off to the slammer. And while it's not against Manny Pacquiao as so many boxing enthusiasts have called for, Cotto presents an interesting challenge.

"Money," at 42-0, looks like an unstoppable force. His defensive style and unmatched speed have made him unbeatable throughout his illustrious career. But Cotto is younger, more powerful, and has a size advantage. Now the pair are set to square off later this evening (May 5, 2012) from the MGM Grand Garden Arena in Las Vegas, Nevada, in a major prize fight that will air on HBO pay-per-view (PPV), beginning at 9 p.m. ET.

So how did both men prepare for tonight's showdown? The HBO 24/7 crew followed both fighters and found out in the lead-up to tonight's explosive match-up. Watch every episode to catch yourself up after the jump.
