The Ultimate Fighting Championship (UFC) gets its chance to shine on network television later this evening (Sat., Dec. 8, 2012) with its UFC on Fox 5: "Henderson vs. Diaz" event taking place at the KeyArena in Seattle, Washington, and featuring Ben Henderson battling Nate Diaz for the lightweight championship.
But once the mixed martial arts (MMA) boys are through, the boxing big hitters take center stage on pay-per-view (PPV) at the MGM Grand Garden Arena in Las Vegas, Nevada, at 9 p.m. ET.
Manny Pacquiao returns to the ring on a relatively short turnaround from his controversial decision loss to Timothy Bradley to battle Juan Manuel Marquez for the fourth and final time to, hopefully, settle the score once and for all in their historic rivalry.
They couldn't crown a clear winner through 36 rounds. Maybe they just needed 12 more.
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 below (it's a playlist, which means all three videos are in the one player) to catch yourself up.
Remember, too, that MMAmania will have LIVE results, coverage and updates of "Pacquiao vs. Marquez 4" all night, starting with the HBO broadcast at 9 p.m. ET RIGHT HERE.
See you then!
