They're back at it again.
The dynamic boxing duo of Manny Pacquiao and Juan Manuel Marquez are primed for fight number four in their fantastic series of matches spanning 12 years and 36 rounds of action. Throughout all of that time, a clear winner has yet to come forward.
Hopefully, that happens tomorrow night (Sat., Dec. 8, 2012) at the MGM Grand Garden Arena in Las Vegas, Nevada, when the two hook 'em up for the final time.
Before all that, though, they did the customary staredown thing at the official weigh-in event that took place earlier today in "Sin City." After hitting their respective marks, the friendly rivals squared off to get hype for the pending showdown.
