Eight-time, eight-division champ Manny Pacquiao battles three-time world champ Juan Manuel Marquez for the fourth time. Theirs is a storied rivalry which dates back to 2004, when they fought for a super featherweight title. Every fight has been a closely contested affair — and this one, at welterweight, may settle things for good. Also on the card: Yuriorkis Gamboa faces Michael Farenas, Miguel Vazquez battles Mercito Gesta, and Javier Fortuna takes on Patrick Hyland. And featuring the pro debut of Jose Ramirez.
