Juan Manuel Marquez and Timothy Bradley are set to meet tomorrow night live on HBO pay-per-view in a bout for Bradley's welterweight title. Before the two can fight, they need to hit the scales to make it official. That weigh-in will take place today and you can watch it live, streaming right here.  The weigh-in show kicks off at 5:30 p.m. ET with the two main event fighters set to hit the scales at 6:15.  Neither man has much of a history of weight trouble, but the atmosphere and interaction during the staredown. And, against Manny Pacquiao it was seeing Marquez step onto the scales that shocked everyone as he was significantly more muscular, a factor that played a part in his thunderous knockout of the Filipino superstar.  Make sure to share your thoughts on the weigh-ins in the comments and check back throughout the weekend for live results, fallout and much more.
