The rematch is on. Moments ago in Las Vegas, Manny Pacquiao (44-3-2, 35 KOs) weighed in at 130-pounds, Marco Antonio Barrera (63-5, 42 KOs) also weighed in at 130-pounds on the nose.

The two will now meet tomorrow night in the main event of an HBO pay-per-view from the Mandalay Bay Resort & Casino in Las Vegas. The fight is a rematch of their 2003 meeting, which Pacquiao won by TKO.
