The April 12 rematch between WBO welterweight beltholder Tim Bradley and Manny Pacquiao will be preceded the HBO premiere of Face Off with Max Kellerman, starting Saturday at 11:45 p.m., ET/PT.

In his past three fights, Bradley dethroned Pacquiao by split decision in June 2012, rose from a 12th-round knockdown to unanimously decision Ruslan Provodnikov in March 2013 and then won a split-decision over four-division titlewinner Juan Manuel Marquez in October.

After the Bradley fight, in December 2012, Pacquiao lost by sixth-round stoppage to Marquez, against whom Pacquiao is 2-1-1, before winning a unanimous decision over Brandon Rios in his most recent fight last November.

The WBO has declared that the winner of Bradley-Pacquiao II must face that between Marquez and Mike Alvarado, who will fight on May 17.
