Former bantamweight and featherweight champion Rafael Marquez (39-6, 35KOs) was advised by way of a phone from the United States, that his next opponent will be Mike Oliver (24-2, 8KOs) on June 4 at the Staples Center in Los Angeles. Marquez vs. Oliver takes place on the undercard to Julio Cesar Chavez Jr.'s world title bout against WBC middleweight champion Sebastian Zbik of Germany. The fight is Rafael's first appearance since last November's TKO defeat to Juan Manuel Lopez.
